Implementation of Data and Sinus Curves maximum

Dear community,

i am still pretty new to matlab and have a problem.

I would like to write an evaluation script for measurements. I have a dataset with 6 columns and depending on the measurement different target rows.

Column 1,3,5 are always the time and therefore it is enough to transfer column 1. Column 2,4,6 are Y1,Y2,Y3.

I would like to plot Y2 over Y1 after the readout and then get the high point of the sinus curves of the Y2 output. For this I need the corresponding time and Y3 value.

As you can see I need quite a lot...

But at the moment I still have problems to insert the data correctly...

%% Read in the data

fileName = 'Test_Excel.txt';

fid= fopen (fileName, 'r')

content = textscan(fid, '%s%s%d%s%d%s','delimiter',',');

%content = textscan(fid,'%s','delimiter',';'); (this one seems to work better but ..not really)

fclose(fid);

content=[content{:}];

After inserting the Data i thought i should split the data

I would have done it that way

%%Aufteilen der Daten

i=5; j=1;

while i <= length(content)

Zeit(j)= content(i);

i=i+6;

j=j+0;

end

i am a bit desperate and need tips and help. Thanks in advance.

It sounds like the islocalmax function may be of use to you.
