mtlb_triu — 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.
