WebIn Python, we can implement a matrix as a nested list (list inside a list). We can treat each element as a row of the matrix. For example X = [ [1, 2], [4, 5], [3, 6]] would represent a 3x2 matrix. First row can be selected as X [0] and the element in first row, first column can be selected as X [0] [0]. WebThe matrix in the example above has three rows, each with two columns. If you want to try to multiply two matrices (x and y) by each other, you'll need to make sure that the number of columns in x is equal to the number of rows in …
