nzmax
is the number of nonzero entries in the sparse Matrix and therefore the length of the ir
array.
If a Matrix is full, mxGetNzmax
returns an indeterminate value.
mxSetNzmax
does not affect the length of the ir
array - it is up to you to make sure it is consistent.
mxGetNzmax
and mxSetNzmax
allow you to get and set the value of nzmax
. See the "Matrix Data Structure" section in Chapter 1 for more information on sparse Matrices and nzmax
.
