plot columns of matrix

suppose I have a 4x100 matrix Ctrack. The four rows each correspond to a different variable, and they change with time from one column to the next. How would I plot it so that on the same plot i have four different curves showing how each variable changes across the different columns?

Filip - from plot,

plot(Y) creates a 2-D line plot of the data in Y versus the index of each value.

...

If Y is a matrix, then the plot function plots the columns of Y versus their row number. The x-axis scale ranges from 1 to the number of rows in Y.

In your case, you want to plot the rows of Y versus their column number. So perhaps try transposing the data and do as

plot(Ctrack');
