mtlb_min — Matlab min emulation function
Matlab and Scilab min
behave differently in some particular cases:
With complex values: Matlab min
can be used with complex values but not Scilab function.
When called with one input: Matlab min
threats values along the first
non-singleton dimension but Scilab threats all input values.
When called with two inputs: if one is an empty matrix, Scilab returns an error message but Matlab returns [].
When called with three inputs: if dim
parameter is greater than number of
dimensions of first input, Scilab returns an error message and Matlab returns the first input.
The function [r[,k]] = mtlb_min(A[,B[,dim]])
is used by
mfile2sci
to replace [r[,k]] = min(A[,B[,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_min
calls:
When called with one input, if A
is a vector or a scalar
[r[,k]] = mtlb_min(A)
may be replaced by min(A)
When called with one input, if A
is a matrix
[r[,k]] = mtlb_min(A)
may be replaced by min(A,"r")
When called with two inputs, if A
and B
are real matrices and not empty matrices
[r[,k]] = mtlb_min(A,B)
may be replaced by min(A,B)
When called with three inputs, if dim
is lesser than the number of dimensions of A
[r[,k]] = mtlb_min(A,[],dim)
may be replaced by min(A,dim)
Caution: mtlb_min
has not to be used for hand coded functions.
