Matlab triu emulation function


Matlab and Scilab triu behave differently in some particular cases:

  • With complex input: Matlab triu can be used with complex data but not Scilab one.

  • With character strings inputs: due to the fact the Matlab and Scilab do not consider character strings in the same way, Scilab and Matlab triu do not give the same results for this type of input.

  • With boolean inputs: Matlab triu can be used with boobean data but not Scilab one.

The function mtlb_triu(x,k) is used by mfile2sci to replace triu(x,k) 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_triu calls:

  • If X contains real double values mtlb_triu(x,k) may be replaced by triu(x,k)

  • If X contains boolean values mtlb_triu(x,k) may be replaced by triu(bool2s(x),k)

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