FreeMat LAB Introduction

The most common use of the plot command probably involves the vector-matrix paired case. Here, we generate a simple cosine, and plot it using a red line, with no symbols, which resulted in above graph. 

I plotted multiple sinusoids (at different frequencies). First, I constructed a matrix, in which each column corresponds to a different sinusoid, and then plot them all at once

Here's an example of Matrix on freemat
