sum (Matlab function)
Sum of array elements
Particular cases
- M=sum(A)
Scilab sum(A) returns the sum of all components of A. So, if A is a vector, then Scilab and Matlab work in the same way. If A is a matrix, Scilab sum(A) gives the sum of all elements of A but Matlab returns the sum of each column. Finally, if A is a multidimensional array, Matlab works on the first non-singleton dimension of A what Scilab does not. So, to be sure to find a Scilab equivalent for Matlab call to sum it is better to precise dimension on which to work.
- M=sum(A,dim)
In Scilab dim=1 is equivalent to dim="r" and dim=2 is equivalent dim="c". In Matlab, dim can be greater then the number of dimension of A (in this case, M=A), in Scilab you will get an error message.
