UINT32 UINT32 Convert to Unsigned 32-bit Integer Usage Converts the argument to an unsigned 32-bit Integer. The syntax for its use is y = uint32(x) where x is an n-dimensional numerical array. Conversion follows the general C rules (e.g., if x is outside the normal range for an unsigned 32-bit integer of [0,4294967295], the least significant 32 bits of x are used after conversion to an integer). Note that both NaN and Inf both map to 0.
