mtlb_uint8

Matlab uint8 emulation function

Description

Matlab and Scilab uint8 behave differently in some particular cases:

• With complex input: Matlab uint8 can be used with complex values what Scilab function can not.
• With %inf: Matlab uint8 returns 255 and Scilab returns 0.

The function mtlb_uint8(A) is used by mfile2sci to replace uint8(A) when it was not possible to know what was the input while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace mtlb_uint8 calls:

• If A does not contain %inf values mtlb_uint8(A) may be replaced by uint8(A)

Caution: mtlb_uint8 has not to be used for hand coded functions.
