| ) |  |

Add a field to an array of struct.

Parameters

  mlArr | Pointer to an `mpsArray` of struct.

Returns
  Field number on success, or `-1` if inputs are invalid or an out-of-memory condition occurs.

## ◆ mpsArrayToString()

char * mpsArrayToString | ( | const mpsArray * | mlArr | ) |

Copy the character data of a string array into a C-style string.

Parameters

Determine how many elements there are between the beginning of an array and a given element.

Arrays in MATLAB are stored column-major, so accessing the elements of an `mpsArray` using standard C indexing will produce a transposed array. This function accepts row-major dimension subscripts and calculate the proper column-major index to the the desired value.

Parameters

  mlArr | Pointer to an `mpsArray`.
  nsubs | Number of elements in the subs array.
  subs | Array of integers. Each value in the array specifies that dimension's subscript.
