This module covers basic operations in LabVIEW MathScript.

Basic operations on numbers

LABVIEW MATHSCRIPT has many arithmetic operations and functions built in. Most of them arestraightforward to use. The Table below lists some commonly used scalar operations; in this table, x and y are scalars. (A scalar is a single number.)

Common scalar mathematical operations in labview mathscript
Operation LABVIEW MATHSCRIPT
x y x-y
x y x+y
x y x*y
x y x/y
x y x^y
e x exp(x)
log10 x log10(x)
ln x log(x)
log2 x log2(x)

Expressions are formed from numbers, variables, and these operations. The operations have different precedences. The ^ operation has the highest precedence; ^ operations are evaluated before any other operations. Multiplication and division have the next highest precedence, and addition and subtraction have the lowest precedence. Precedence is altered by parentheses; expressions within parenthesesare evaluated before expressions outside parentheses.

The Table below shows several mathematical formulas, the corresponding LABVIEW MATHSCRIPT expressions, and the values that LABVIEW MATHSCRIPT would compute for the expressions.

Example labview mathscript expressions
formula LABVIEW MATHSCRIPT Expression Computed Value
5 2 4 2 5^2+4^2 41
5 4 2 (5+4)^2 81
2 3 4 5 (2 + 3)/(4 - 5) -5
log10 100 log10(100) 2
ln 4 2 3 log(4*(2+3)) 2.9957

Basic operations on matrices

In addition to scalars, LABVIEW MATHSCRIPT can operate on matrices. Some common matrix operations are shown in the Table below; in this table, M and N are matrices.

Common matrix mathematical operations in labview mathscript
Operation LABVIEW MATHSCRIPT
M N M*N
M -1 inv(M)
M T M'
det( M ) det(M)

LABVIEW MATHSCRIPT functions length and size are used to find the dimensions of vectors and matrices, respectively.

LABVIEW MATHSCRIPT can perform an operation on each element of a vector or matrix. To perform an arithmetic operation on each element in a vector (or matrix), rather than on the vector (matrix) itself, then the operator should be preceded by".", e.g .* , .^ and ./ .

Let A 1 1 1 1 . Then A^2 will return AA 2 2 2 2 , while A.^2 will return 1 2 1 2 1 2 1 2 1 1 1 1 .

Given a vector x, compute a vector y having elements y n 1 x n . This can be easily be done in LABVIEW MATHSCRIPT by typing y=1./sin(x) Note that using / in place of ./ would result in the (common) error Matrix dimensions must agree .

Complex numbers

LABVIEW MATHSCRIPT has excellent support for complex numbers with several built-in functions available. The imaginaryunit is denoted by i or (as preferred in electrical engineering) j . To create complex variables z 1 7 and z 2 2 e simply enter z1 = 7 + j and z2 = 2*exp(j*pi)

The Table below gives an overview of the basic functions for manipulating complex numbers, where z is a complex number.

Manipulating complex numbers in labview mathscript
LABVIEW MATHSCRIPT
Re( z ) real(z)
Im( z ) imag(z)
z abs(z)
Angle( z ) angle(z)
z * conj(z)

Other useful details

  • A semicolon added at the end of a line tells LABVIEW MATHSCRIPT to suppress the command output to the display.
  • LABVIEW MATHSCRIPT Version 1.0 is case sensitive for both variables and functions; for example, b and B are different variables and LABVIEW MATHSCRIPT will recognize the built-in function sum but not SUM . In previous versions, LABVIEW MATHSCRIPT was not case sensitive for function names.
  • Often it is useful to split a statement over multiple lines. To split a statement across multiple lines, enter three periods ... at the end of the line to indicate it continues on the next line.

Splitting y a b c over multiple lines. y = a... + b...c;

please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
