mtlb_sum
Matlab sum emulation function
Description
Matlab and Scilab sum
behave differently in some particular cases:
When called with one input: Matlab
sum
treats the values along the first non-singleton dimension of input while Scilabsum
threats all values of input.When called with two inputs: Matlab
sum
can be used with second input giving a non-existing dimension of first input while Scilabsum
returns an error message.
The function mtlb_sum(A[,dim])
is used by
mfile2sci
to replace sum(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_sum
calls:
When called with one input, if
A
is an empty matrix, a scalar or a vector,mtlb_sum(A)
may be replaced bysum(A)
When called with one input, if
A
is a not-empty matrix,mtlb_sum(A)
may be replaced bysum(A,1)
When called with one input, if
A
is a multidimensional array,mtlb_sum(A)
may be replaced bysum(A,firstnonsingleton(A))
When called with two inputs, if
dim
is lesser than the number of dimensions ofA
mtlb_sum(A,dim)
may be replaced bysum(A,dim)
Caution: mtlb_sum has not to be used for hand coded functions. |
