// Number of columns?
ResNbColumns = MatNbColumn("MyMatrix")
Syntax
<Result> = MatNbColumn(<Matrix>)
<Result>: Integer
Number of columns found in the specified matrix.
<Matrix>: Character string
Name of the matrix to be used, defined with MatCreate.
Remarks
The matrix existence is not checked. To check the matrix existence, use
MatExist.
Caution:
MatNbColumn returns no error code. To find out whether errors have been generated when returning the number of columns, use
MatError. To get more details on the error, use
ErrorInfo with the
