Writing Target Language Files

3-42

For example, given the 2-by-3 matrix

model.h defines:

typedef struct Parameters_tag = {

struct { /* S-function */

real_T matSize[2];

real_T mat[3][2];

} sfuncBlock;

struct { /* any non S-function */

real_T mat[2][3];

} nonSfuncBlock;

} Parameters;

model.prm

declares:

Paramters rtP = {

{ 2, 3 },

{ 1, 4, 2, 5, 3, 6 },

{ 1, 2, 3, 4, 5, 6 }

};

The Target Language Compiler access routines, LibBlockMatrixParameter

and

LibBlockMatrixParameterAddr, return:

LibBlockMatrixParameter(mat, "", "", 0, "", "", 1) returns

non-S-function: 2

S-function: 2

LibBlockMatrixParameterAddr(mat, "", "", 0, "", "", 1) returns

non-S-function: &rtP.nonSfuncBlock[0][1];

S-function: &rtP.sfuncBlock[1][0];

Matrix parameters are like any other TLC parameters in that only those

parameters explicitly accessed by a TLC library function during code

generation are placed in the parameters structure. So,

matSize is not declared
