Matlab plotmatrix

For an exercise at school, I'm trying to plot a function where the variable is a matrix. The function is very simple: y=x^4 The matrix, x, is 0:0.01:20 so it has a range from 0 to 20, and there are 2000 between them.

Then you can create a basic 3D scatter plot: scatter3 (m (:,1), m (:,2), m (:,3)) However, this is not what you want, because points are in the same colour. To add colour based on your colouring logic, you should firstly create a color matrix using one of the MATLAB's built-in color maps. Here I use jet: myc = jet (n);Compute the open-loop poles and check the step response of the open-loop system. Pol = pole (sys) Pol = 2×1 complex -0.5000 + 1.3229i -0.5000 - 1.3229i. figure (1) step (sys) hold on; Notice that the resultant system is underdamped. Hence, choose real poles in the left half of the complex-plane to remove oscillations.Create Scatter Plot Matrix with Two Matrix Inputs.
