mtlb_diag - Matlab diag emulation function (original) (raw)

Description

Matlab and Scilab diag behave differently in some particular cases:

• With character string matrices: Scilab diag function considers each character string as an object while Matlab considers each character individually.

The function y = mtlb_diag(x[,dim]) is used bymfile2sci to replace y = diag(x[,dim]) 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_diag calls:

• If x is not a character string matrixy = mtlb_diag(x[,dim]) may be replaced by y = diag(x[,dim])

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