Swift matrix sum

Question

I\'m trying to develop a func which allows to sum two matrix if they are equals to the same dimension, but I get an error \"EXC_BAD_INSTRUCTION\" on the try.

Here is

Answer 1

Actually your error is Index out of range

Replace your extension with this code.

extension Matrix: Operation {

    mutating func sumWith(matrixB: Matrix) throws -> Matrix {

        guard self == matrixB else { throw RisedError.DimensionNotEquals }

        for row in 0...self.rows - 1 {
            for column in 0...self.columns - 1 {
                self[row, column] = matrixB[row, column] + self[row, column]
            }
         }
        return self
    }
}

Hope it would solve your problem.
