Plot signal from list of data in MATLAB

[kay310]

I want to load a .mat file which contain 500 column of data in it and plot the signal out through the GUI using .m file.
Can anyone help me on the code?

So you have a set of y-data of 300. Make an x vector of size 300 that goes from 0 to 300 and then plot(x,y);

I'm now actually unable to load the .mat file using 'load' command.
I doing this way in m-file:

load filename;
[x,y] = size(filename);
t = 1:y;
plot(t, filename);

%the filename is in .mat format

can anyone help me in load a .m file and plot the signal out?

using this way:
[Filename, PathName] = uigetfile('*.m','Select the M-file');

Sure, I can help you with the code for plotting the signal from a list of data in MATLAB. First, you will need to load the .mat file using the "load" function. This will load the data into a variable, let's say "data", which will have 500 columns as you mentioned.

Next, you can use the "plot" function to plot the signal. You will need to specify which column of data you want to plot. For example, if you want to plot the first column, you can use the code:

plot(data(:,1))

This will plot the signal from the first column of your data. You can also add labels, titles, and customize the plot as desired.

To create a GUI for plotting, you can use the "guide" function in MATLAB. This will open a GUI development environment where you can add buttons, sliders, and other interactive elements to your plot. You can then use the "plot" function within the GUI code to plot the signal from the desired column of data.

I hope this helps. Let me know if you have any further questions.
