vebe (Mu Analysis and Synthesis Toolbox)

vebe	Examples See Also

Perform element-by-element operations on CONSTANT and VARYING matrices

Syntax

out = vebe('oper',matin)

Description

The vebe function allows any single argument MATLAB element-by-element arithmetic command to operate on a VARYING matrix. The first input argument, oper, is the character string defining the MATLAB element-by-element command and matin is the VARYING matrix on which the command is applied. vebe calls the MATLAB eval command to execute the string command. Some standard MATLAB comands compatible with vebe are sin, abs, real, imag, and gamma.

Examples

In this example of vebe, the real part of a matrix is found along with gamma of each matrix element.
