Built-in Functions in MATLAB ® Environment MATLAB ® provides a rich
library of built-in functions to provide convenience to the programmer for data manipula-
tion. It is the simplicity of data handling with this rich set of built-in functions and the sim-
®
plicity of I/O handling that makes MATLAB an attractive computational engineering tool.
The following built-in functions are useful in data generation
>> A = zeros(5,5) ;
% all elements of A matrix, 5x5, are zero
