Examples of C MEX-Files

2-17

This example takes an m-by-n structure matrix as input and returns a new

1-by-1 structure that contains these fields:

•String input generates an m-by-n cell array

•Numeric input (noncomplex, scalar values) generates an m-by-n vector of

numbers with the same class ID as the input, for example

int, double, and

so on.

* =============================================================

* phonebook.c

* Example for illustrating how to manipulate structure and cell

* array

* Takes a (MxN) structure matrix and returns a new structure

* (1x1) containing corresponding fields:for string input, it

* will be (MxN) cell array; and for numeric (noncomplex, scalar)

* input, it will be (MxN) vector of numbers with the same

* classID as input, such as int, double etc..

* This is a MEX-file for MATLAB.
