Hi,
I've 2 sets of results from another software. Say Design1 and Design2. In each Design I've a set of X and Y values to plot. For Design1 the length is 1mm and for design2 the length is 2mm. So now, is it possible, If I type in 1mm it has to select design1 and plot the values under it. I've more than 200 Design results with x and y values under each. So I need to write a program so that If i type in a value, it'll select which design it is and plot the value.
Could someone pls help a little.

Will the design number always be equal to the length? Or might Design163 correspond to a length of 250 mm?
If the numbers are always the same, you can simply open the file by
n=7;
XY=dlmread(sprintf('%s\\Design%d.txt',currentpath,n));
Alternatively, you can of course also ask for the number with the inputdlg.
If the design number doesn't directly link to the length, you need to store the correlation additionally. Say, Design1-4 link to 1,2,5,10 mm, the correlation would be
c=[1 52 5 10];
l=5; %length in mm
n=find(c==l);
then read as shown above.
Plotting of course by
plot(XY(:,1),XY(:,2))

Ok, in this case you can use the following code:
fid=fopen('example.csv');
firstline=fgetl(fid);
ncolumns=1+sum(firstline==',');
ndesigns=length(regexp(firstline,'[^,]*'));
nparams=ncolumns-3*ndesigns-1;
data=textscan(fid,[repmat('%s%s%*s',1,ndesigns) '%*s' repmat('%s',1,nparams)],'delimiter',',','collectoutput',1);
fclose(fid);
values=str2double(reshape(data{1}(2:end,1:2*ndesigns),size(data{1},1)-1,2,ndesigns));
parameters=str2double(data{1}(2:ndesigns+1,2*ndesigns+1:end));
inputparams=str2double(inputdlg({'Length';'Width';'Thickness';'Temperature';'x';'y';'z'}))';
design=find(all(bsxfun(@eq,parameters,inputparams),2));
outputdata=values(:,:,design);
plot(outputdata(:,1),outputdata(:,2))
I hope this will also work with your larger file.

Just in your GUIDE m code. You have the line where you define inputparams=... in the puhsbutton1_Callback. Replace this line by the ones I have posted.
