Sum of a matrix, even or odd
- by user1790201
This function receives a numeric matrix represented as a list of rows, where each row is in turn a list. Assume that it is a square matrix: all rows have the same length and there are as many rows as elements in each row. Also assume that the matrix is at least of dimension 2 by 2 (i.e. minimally the matrix has 2 rows with 2 elements each)
The function should return a list with as many elements as number of rows. Element i in the resulting list should have the sum of the values in row i.
For example, if the matrix is
1 2 3
10 20 30
100 200 300
then this function should return the list [6,60,600]
That is,
addValuesInAllRows( [ [1,2,3], [10,20,30], [100,200,300] ] ) should return [6,60,600]
Isn't this sort of similar but how would you sum up the list individually
