A similar discussion holds regarding the two middle plots in Figure 2 . The log version on the bottom identifies the location of the minima more closelythan does the linear plot at the top.

The log of the surface is flatter

You can also see from the bottom right image of Figure 2 that the central peak of the log of the surface is much broader than the central peak for the rawsurface at the top right. This is indicated by the width of the white and yellow areas in the log version as compared to the white and yellow areas in the rawversion.

In addition, the elevations of the log data for the minor peaks at the four sides are almost as high as the elevation of the central peak, as indicated bythe orange or yellow color at the top of the minor peaks.

The elevations of the tops of the four minor peaks at the corners are perhapsseventy-five percent of the elevation of the central peak as indicated by the pinkish color of those minor peaks in the log version.

(Recall that the elevation of the minor peaks at the corners is only about two levels up from the lowest elevation in the raw surface data.)

All of this flattening was caused by converting the raw surface elevations to the log of the surface elevations before producing the surface plot.

Multiple plotting formats are useful

A plotting format that works best for one surface doesn't necessarily work best for all surfaces. Therefore, it is useful for the program to be able toplot the same surface using different plotting formats.

Extremely easy to use

One of the main objectives in the development of this class was to make it very easy to use. No fancy programming is required to use the class and producethe plots. All that is required is to instantiate an object of the class named ImgMod29 , passing an array of data to be plotted along with a few other parameters to the constructor. Basically the parameters (in addition to the data array) specify:

  • Which of the three main formats to use, Grayscale, Color Shift, or Color Contour.
  • Whether or not to convert to logarithmic values before plotting.
  • Whether or not to draw the red axes shown in Figure 1 and Figure 2 .
  • How many pixels in the final output should be used to represent a single point on the surface. (For example, the plots in Figure 1 and Figure 2 use a square of nine pixels to represent each point on the 3D surface.)

When an object of the class ImgMod29 is instantiated, everything else happens automatically and the plot is displayed on the computerscreen as illustrated by any one of the images in Figure 1 or Figure 2 .

Multiple plots

If multiple plots in different formats are needed for a given set of data, all that is required is to instantiate multiple objects of the class named ImgMod29 passing the same data array with different parameters to the constructor for each plot. Be aware, however, that all of the plots willbe produced in a stack in the upper left corner of the screen. You must physically move the plots on the top in order to be able to view the plots lowerdown in the stack.

Questions & Answers

explain scarcity
Richard Reply
scarcity occurs when there are not enough resources to satisfy human's needs and wants therefore we need to allocate our resources using the price mechanism.

it maybe define as the amount or quantity of goods and services which a consumer is willing to buy with the ability to pay at a given price at a particular time

why is economics a science
Isaac Reply
Because science is all about thinking by making models whether a computational or Mathematical. Economics is a social sciences because it effects society but to understand Economics we use maths so it is a Science

yeah
Habib
so what is the disadvantages of mix economic system
Habib
Economics is regarded as a social science because it uses scientific methods to build theories that can help explain the behaviour of individuals, groups and organisations.
Ali
The question is: why is Economic a "science" and not why is economics a "social science?" Alright folks?
Xavier
In my own understanding of why economics is a science it bcz it deals mainly on human resources just like biology that deals in the human body why economics is science it also deals on the management of human resources all over the world bcz without economics there will be no human resources
Ogbonnaya
what is technology
Nkwenti
my response to the earlier question is, economics is a science but not a pure science like biology, chemistry and physics. The reason is that those pure science study inanimate object while economics study human being, their experiment are predictable.
raimi
Economics is a social science subject that shows the relationship between ends and scarce means with their alternative uses

what is Equilibrium?
Fatima Reply
it means equal price and equal quality
Arthur
thank u Arthur!

Fatima
Thanks
Moses
Equilibrium is a state of balance in an economy. In as far as market forces are reasonably concerned, equilibrium means the state at which the quantity of goods supplied is equal to the quantity of goods demanded.

difference between demand and supply
Adeyemi Reply
Demand- It is the desire of a buyer and his ability to pay for a particular commodity at a specific price. Supply- It is quantity of a commodity which is made available by the producers to its consumers at certain price.
Ali
yes OK thank you dear
Gyamfua
Demand can be defined as the ability a buyer is willing and able to pay at a specific price and in agiven period of time Supply can be defined as the ability the producer is willing to supply with a specific price

formula for price elasticity of demand
Emilia Reply
Suppose that a soft drink company calculates that the demand for a bottle of its soda increases from 100 to 110 after the price is cut from $2 to $1.50.
Ali
The price elasticity of demand is calculated as the percentage change in quantity demanded (110 - 100 / 100 = 10%) divided by a percentage change in price ($2 - $1.50 / $2).
Ali
what does unit price mean
Lognyuu Reply
unit price is the price for a single unit of measure of a product sold in more or less than the single unit.
Gyamfua
How do we find unit price?
Gyamfua
divide total cost by total units
Ali
I don't understand the unit Price
global
which one how find or what
Gyamfua
sorry how to find it or what
Gyamfua
please how do we find the unit price
Tabi
unit price or cost is the price per item when you purchase in a bulk
Gyamfua
example assuming you bought a pack of matches is 1gh but the pack contains 10 boxes so the price per the box is called the unit price ie divide 1gh by the number of matches boxes in the pack to get unit price/cost. NB unit here means one so price per 1
Gyamfua
you will divide total cost by total unit
Weto
yes please
Gyamfua
yes, in the matches scenario it's 1gh/10boxes which is equal to 0.10ps so the unit price of the one box of the matches is ten Ghana pesewas
Gyamfua
Thank you I now understand

Given that the price of a product has rose, the demand of the the product will decrease. Thus leads to a downward-sloping demand curve
M_geshnee Reply
The demand of consumers
M_geshnee
No demand curves have différent shapes. For examole guven that price of a product increase, the demand of that product will decrease thus It will lead to a downward sloping curve conversely there can be also a rightward shift in the demand curve when price a the good decrease demand will increase
