What is the correct syntax for num2str

Hi guys,

I am having some problems with the num2str. I am trying to read/save/move file names like Dataset_0.4_u1 to u5.csv ,Dataset_0.204_u1 to u5.csv and Dataset_0.242_u1 to u5.csv.

I tried with file name or using the num2str and have all them into one single loop, if possible.

filename=('Dataset' (num2str(set)) 'U' (num2str(Manoev)) );
Dataset(num2str(set))U(num2str(Manoev))=[[Data(num2str(set))]{1,Manoev}]

'set' corresponds to 0.4,0.204 and 0.242, 'manoev' is just from 1 to 5.

Thanks Regards

[Thorsten]

set = [0.4 0.204 0.242];
manoev = 1:5;

 for i = 1:numel(set)
   for j = 1:numel(manoev)
     filename = ['Dataset_' num2str(set(i)) '_U_' int2str(manoev(j)) '.csv'];
     Data(i, j) = csvread(filename);
   end
 end

it worked with the xlsread. Thanks

First, set is a very important MATLAB function so I would advise against shadowing it with a variable.

You would need to concatenate your strings with [] or strcat:

v = [1.1 3]
filename = ['Dataset' num2str(v(1)) 'U' num2str(v(2)) '.csv']

Frankly through, I would just use sprintf instead of num2str:

filename = sprintf('Dataset%gU%g.csv',v)

Thanks.

Is it possible to use the same syntax with the save function as well? After each five, all saved into one according to (0.4 0.204 and 0.242)
