Returns

Logical 1 (true) if the array can contain numeric data. The following class IDs represent storage types for arrays that can contain numeric data:

  • mxDOUBLE_CLASS

  • mxSINGLE_CLASS

  • mxINT8_CLASS

  • mxUINT8_CLASS

  • mxINT16_CLASS

  • mxUINT16_CLASS

  • mxINT32_CLASS

  • mxUINT32_CLASS

  • mxINT64_CLASS

  • mxUINT64_CLASS

Logical 0 (false) if the array cannot contain numeric data.

Description

Call mxIsNumeric to determine whether the specified array contains numeric data. If the specified array has a storage type that represents numeric data, mxIsNumeric returns logical 1 (true). Otherwise, mxIsNumeric returns logical 0 (false).

Call mxGetClassID to determine the exact storage type.
