AI Drawing Prompt Reference

Draw a diagram showing the multiplication of a 3x3 matrix by a 3x1 column vector. The matrix rows are [1,1,1], [4,2,1], [9,3,1]; the column vector is [18,12,2]. Use a coordinate grid background, enclose the matrix and vector in square brackets, and connect them with an equals sign to the resulting column vector. Each component of the result is computed by summing the products of corresponding entries from the row and the vector. Label the calculation steps clearly. The layout should emphasize the row-by-column rule of matrix multiplication.
