mtlb_upper

Matlab upper emulation function

Description

Matlab upper(A) and Scilab convstr(A,”u”) behave differently in some particular cases:

• If A is not a chacarter string matrix: Matlab upper can be used with a not-character-string A but not Scilab convstr.

The function mtlb_upper(A) is used by mfile2sci to replace upper(A) when it was not possible to know what were the inputs 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_upper calls:

• If A is a character string matrix mtlb_upper(A) may be replaced by convstr(A,”u”)
• If A is not a character string matrix mtlb_upper(A) may be replaced by A

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