Could anyone please let me know that why i can t plot this spectrum mat file kindly if someone show me the procedure for plotting mat files.
How to plot mat file in matlab.
Y exp x sin 2 x 3.
By the way in this spectrum mat file there are two columns e g x axis frequency and y axis scale and 401 rows.
A struct is like a container for variables and it contains fields in which the values are saved.
An exploratory plot of your data enables you to identify discontinuities and potential outliers as well as the regions of interest.
The interval is written lower bound upper bound.
The proper syntax for fplot is.
If you load a mat file this way you will see that s is a variable of the type struct.
Plot x y axis 0 10 1 1 when you run the file matlab generates the following graph generating sub plots.
Better yet we should be able to tell matlab to read and use the column headings when it creates the plot legend.
When you create an array of plots in the same figure each of these plots is called a subplot.
So you will basically type in the name of the function first and then type in the interval.
You can not plot a mat file what you can do is.
Fplot name of function interval.
A better solution is to have matlab read the file without destroying the labels.
Matlab will pick the interval.
Be sure you save the file as an excel workbook in order to have the proper file format for the import.
The data is a sequence of samples.
One solution is the file readcoldata m.
Step 1 open a fresh matlab screen.
The full text of that function won t be reproduced here.
The from file block loads data from a mat file into a model and outputs the data as a signal.
The from file block icon shows the name of the mat file that supplies the data to the block.
The matlab figure window displays plots.
The pathway for the folder typically is.
If you do not know the interval then you can just put fplot f.
Be sure to record the name of the excel file for later use step 3 save the excel file into your matlab folder.
To make the process of importing and graphing data easier clear any text in the command window with the command clc step 2 open your desired excel file.
Create a script file and type the following code x 0.
After you import data into the matlab workspace it is a good idea to plot the data so that you can explore its features.
Each sample consists of a time stamp and an associated data value.
