mtlb_repmat

Description

There is no Scilab equivalent function for Matlab repmat but there are equivalent instructions.

The function mtlb_repmat(M,m[,n]) is used by mfile2sci to replace repmat(M,m[,n]) 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_repmat calls:

• If A is of Double type and m is a scalar, mtlb_repmat(M,m) may be replaced by ones(m,m).*.M and mtlb_repmat(M,m,n) may be replaced by ones(m,n).*.M

• If A is of Boolean type and m is a scalar, mtlb_repmat(M,m) may be replaced by ones(m,m).*.bool2s(M) and mtlb_repmat(M,m,n) may be replaced by ones(m,n).*.bool2s(M)

• If A is of String type and m is a scalar, mtlb_repmat(M,m) may be replaced by asciimat(ones(m,m).*.asciimat(M)) and mtlb_repmat(M,m,n) may be replaced by asciimat(ones(m,n).*.asciimat(M))

• If A is of Double type and m is a vector, mtlb_repmat(M,m) may be replaced by ones(m(1),m(2),...).*.M

• If A is of Boolean type and m is a vector, mtlb_repmat(M,m) may be replaced by ones(m(1),m(2),...).*.bool2s(M)

• If A is of String type and m is a vector, mtlb_repmat(M,m) may be replaced by asciimat(ones(m(1),m(2),...).*.asciimat(M))

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