mtlb_int16

Matlab int16 emulation function

Description

Matlab and Scilab int16 behave differently in some particular cases:

• With complex input: Matlab int16 can be used with complex values what Scilab function can not.
• With %inf: Matlab int16 returns 32767 and Scilab returns -32768.
• With %nan: Matlab int16 returns 0 and Scilab returns -32768.
• With -%nan: Matlab int16 returns 0 and Scilab returns -32768.

The function mtlb_int16(A) is used by mfile2sci to replace int16(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_int16 calls:

• If A does not contain %inf, %nan or -%nan values mtlb_int16(A) may be replaced by int16(A)

Caution: mtlb_int16 has not to be used for hand coded functions.
