mtlb_beta

Description

Matlab and Scilab beta behave differently in some particular cases:

• With inputs having different sizes: Matlab beta input parameters must have the same size unless one of them is a scalar. In Scilab beta input parameters must have the same size even if one of them is a scalar.

The function mtlb_beta(A,B) is used by mfile2sci to replace beta(A,B) 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_beta calls:

• If A is a scalar but not B Y = mtlb_beta(A,B) may be replaced by C=B;C(:)=A;Y = mtlb_beta(C,B);

• If B is a scalar but not A Y = mtlb_beta(A,B) may be replaced by C=A;C(:)=B;Y = mtlb_beta(A,C);

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