This example shows a MATLAB M-file for plotting the truncated Fourier Series of a square wave. MATLAB supports customizing the appearance and detailing of any graph. I am trying to create a kaiser window for a signal but for some reason, I do not get a appropriate solution for it. The difference is ntitle keeps the text closer to the data, whereas title places the text high above the axes, where it may appear to be an xlabel for to the plot above. The MATLAB command. MATLAB draws a smoother graph − Adding Title, Labels, Grid Lines and Scaling on the Graph MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph. There is now (in r2018b) a function in base MATLAB for placing a title over a grid of subplots. This code based on the governing equation (J.
