mxClearLogical

Clear the logical flag

C Syntax

Arguments
array_ptr
   Pointer to an mxArray having a numeric class.

Description

Use mxClearLogical to turn off the mxArray's logical flag. This flag tells MATLAB that the mxArray's data is to be treated as numeric data rather than as Boolean data. If the logical flag is on, then MATLAB treats a 0 value as meaning false and a nonzero value as meaning true.

Call mxSetLogical to turn on the mxArray's logical flag. For additional information on the use of logical variables in MATLAB, type help logical at the MATLAB prompt.

Example

See mxislogical.c in the mx subdirectory of the examples directory.
