Split cell example.png

Hi

I am interested in being able to extract one of two numbers that is in a cell and split by a semi-colon.

Image is attached indicating which I want to split.

Any help is greatly appreciated.

Many thanks in advance,

Jake - have you already written the code to read the data from the Excel file? If so, are you just reading in the column of interest or all of the columns? Whether you have read it one or all, what is the data type for that column that you wish to split on - is the data being saved as a char/string?

Hi Geoff,

I have written the code to read a number of 'trials' in from a file name '.mot'. Essentially reading in a large structure from something similar to Excel.

I have now established how to split the data, however when I put into a for loop, only the last loop is being saved. Below is the script:

for i=1:nwalks

[Maxpeaks]=findpeaks(Results.Knee_Add_R_Torque(i).waveforms(60:100),'SortStr','descend');

Threshold=Maxpeaks(1,1)*Thold; %Determines the threshold for the findpeaks function

[Results.Knee_Add_R_Torque(i).MaxPeaks, Results.Knee_Add_R_Torque(i).Peaklocationpercent]=findpeaks(Results.Knee_Add_R_Torque(i).waveforms,'MinPeakHeight',Threshold,'MinPeakDistance',width);

end

for i=1:nwalks

Results.Ave=Results.Knee_Add_R_Torque(i).MaxPeaks';

end

Any ideas why the two outputs are being replaced to the last loop?

You need to assign values to elements in a cell array to prevent them from being overwritten

Results.Ave = cell(1,nwalks); % optional initialization for faster execution
for i=1:nwalks 
    Results.Ave{i}=Results.Knee_Add_R_Torque(i).MaxPeaks';
end

Or maybe you are trying to create a single matrix with the values of MaxPeaks. In that case try

Results.Ave = [Results.Knee_Add_R_Torque.MaxPeaks].';
