Hi All,

I am trying ot do something which I think should be pretty easy but I am having a hard time doing it and hope someone can help me out!

I have an Excel sheet with numerous cells of data. I am only interested in certain lines and have figured out how to inport the data into matlab and use it as I please currently creating varriables my self i.e "Probe_1, Probe_2" and performing certain operations to the Probe_x varriables. However, I am trying to automate the creation of the Probe_x varraible for my project to put into a GUI.

I am trying to create a solution that can manage the number of probes, i.e if I change the values of w and h then more Probe Varriables will be created. My end goal is to create a w by h matrix with probe data only when Wt_Speed is above 56.5.

For example if w = 4 and h = 8 then i would have 32 total probes and would want to organize only the values from each Probe when Wt_Speed > 56.5 in a 4x8 matrix.

data = xlsread(Selected_File); %Reads CSV 
w = 3; % horizonatl probes  app.ofHorizontalProbesEditField.Value;
h = 1; % vertical probes app.ofVeritcalProbesEditField.Value;
number_probes= w*h; %
for a = 1:number_probes;
    Probes{a}=data(4:end,(35+a)); %creates a cell of probe data 
end
%current way
 Probe_1= cell2mat(Probes(:,1)); %Total Pressure Probe 1, Psf
 Probe_2= cell2mat(Probes(:,2)); %Total Pressure Probe 2, Psf
 Probe_3= cell2mat(Probes(:,3)); %Total Pressure Probe 3, Psf
 
%% Steady State Data Read
% Read only S.S data
Wt_Speed = data(4:end,25); %Wind Tunnel Speed Readout, Mph
SS_time = find(Wt_Speed>56.5); %finds all instances of mph>56.5
