A Quick Introduction to Matlab

using Matlab. To enter a matrix in Matlab, we’ll just make a 3 by 3 matrix: M = [ 1 -1 1;-6 0 1; 0 -5 -1] The semicolons inside the brackets make new rows in the matrix. We also need a column vector for the voltages. V = [ 0;-11;-10] And that’s all the input data. Now let’s do some algebra. To invert the matrix call. M^-1 % invert the matrix ................
