Hey guys,
I am fairly new to MATLAB. I have some data from a wind tunnel experiment. Each one of my .txt files has 6 rows and multiple columns. The rows represent Fx, Fy, Fz, Mx, My, Mz. I have to use a function/script I already got given to get and plot the Power Spectral Density of each one of them seperately. This is what I have written already.
clc; clear all; close all;
list=dir('*.txt');
for i=1:length(list)
data=importdata(list(i).name);
end
Inside my for loop I have to somehow go through each row, use the PSD function I have and plot the result.
Can someone help me?
Thank you in advance,
Stef

Thank you for the answer Madhan!!!
I have a script/function Fourier_Trans(data,sf,windows). The data input for the function needs to be every row of my .txt file. Moreover, all of this is in a for loop with 7 .txt files. That mean I need 42 graphs as an output.
Can you please advice me on how to proceed?
Thank you,
Stef
