mtlb_find

Matlab find emulation function

Description

Matlab and Scilab find behave differently in some particular cases:

• With column vectors and matrices as input: Matlab find returns column vectors while Scilab returns row vectors.

• When called with three outputs: Matlab find can have three outputs but Scilab not.

The function [i[,j[,v]]] = mtlb_find(B) is used by mfile2sci to replace [i[,j[,v]]] = find(B) when it was not possible to know what was the input 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_find calls:

• When called with one output, if B is a row vector i = mtlb_find(B) may be replaced by i = find(B)

• When called with one output, if B is not a row vector i = mtlb_find(B) may be replaced by i = matrix(find(B),-1,1)

• When called with two outputs, if B is a row vector [i,j] = mtlb_find(B) may be replaced by [i,j] = find(B)

• When called with two outputs, if B is not a row vector [i,j] = mtlb_find(B) may be replaced by [i,j] = find(B);i = matrix(i,-1,1);j = matrix(j,-1,1);

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