Arguments
Description
Call mxSetM
to set the number of rows in the specified mxArray
. Call mxSetN
to set the number of columns.
You can use mxSetM
to change the shape of an existing mxArray
. Note that mxSetM
does not allocate or deallocate any space for the pr
, pi
, ir
, or jc
arrays. Consequently, if your calls to mxSetM
and mxSetN
increase the number of elements in the mxArray
, then you must enlarge the pr
, pi
, ir
, and/or jc
arrays.
If your calls to mxSetM
and mxSetN
end up reducing the number of elements in the array, then you may want to reduce the sizes of the pr
, pi
, ir
, and/or jc
arrays in order to use heap space more efficiently.
