# 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.
