mtlb_int8

Matlab int8 emulation function

Description

Matlab and Scilab int8 behave differently in some particular cases:

• With complex input: Matlab int8 can be used with complex values what Scilab function can not.
• With %inf: Matlab int8 returns 127 and Scilab returns 0.
• With -%inf: Matlab int8 returns -128 and Scilab returns 0.

The function mtlb_int8(A) is used by mfile2sci to replace int8(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_int8 calls:

• If A does not contain %inf or -%inf values mtlb_int8(A) may be replaced by int8(A)

Caution: mtlb_int8 has not to be used for hand coded functions.
