I want to plot a sine wave from a data array.

Hi,

I have a mat file which is full of data extracted from a sine wave. Now, I want to plot one based on this data. How can I do it in MATLAB?

You're going to have to give a lot more details.

A mat file contains variables, so firstly it's unclear what a mat file full of data extracted from a sine wave actually means.

Then it's unclear what one is in I want to plot one.

Hi Mehrdad,

I am assuming that you want to plot a specific variable stored in MAT-file.

My suggestion would be:

1. Since, you cannot plot a mat file directly, you have to load the data to the MATLAB workspace first. For this, you can execute something like the following example:

Data = load('Sine.mat'); % replace 'Sine.mat' with the name of your MAT-file

2. Now you can plot the data, perhaps using the following command:

plot(Data.spec);

where "spec" can be replaced with the variable which you want to plot.

Hope this helps.

Thanks for the answer. I know the question was vague and I apologize.
