mtlb_all
M2SCI function
mtlb_all - Matlab all emulation function
Description
Matlab
all
and Scilab
and
behave differently in some particular cases:
-
-
-
When used with one input (
all(A)
), Matlab
all
treats the values along the first
non-singleton dimension of A as vectors while Scilab
and
treats all A values.
-
When used with two inputs (
all(A,dim)
), Matlab tolerates
dim
to be greater than
the number of dimensions of A while Scilab returns an error message in this case.
The function
R = mtlb_all(A[,dim])
is used by
mfile2sci
to replace
all(A[,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_all
calls:
-
-
-
If
A
is a scalar or a vector
R = mtlb_all(A)
may be replaced by
R = and(A)
-
If
A
is a matrix
R = mtlb_all(A)
may be replaced by
R = and(A,1)
-
If
A
is an hypermatrix
R = mtlb_all(A)
may be replaced by
R = and(A,firstnonsingleton(A))
or by
R = and(A,user_defined_value)
if the first non-singleton dimensions of A is known.
-
If
dim
is less equal to the number of dimensions of A
R = mtlb_all(A,dim)
may be replaced by
R = and(A,dim)
-
If
dim
is greater than then number of dimensions of A
R = mtlb_all(A,dim)
may be replaced by
R = A<>0
if A is not an empty matrix or by
R = A
if A is an empty matrix.
Caution:
mtlb_all
has not to be used for hand coded functions.
