MATLAB: What is the correct syntax for num2str

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

Best Answer

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

Maybe like this:

Data  = rand(7, 25);  % Example data, actually 177x25
Names = {'A 123', 'A 123', 'B 456', 'A 123', 'B 456', 'B456', 'A 123'};
A123 = strcmp(Names, 'A123');
B456 = ~A123;
Set1 = Data(A123, :)
Set2 = Data(B456, :)

Database is not a 3 x 5 matrix but a cell array with 3 x 5 elements. So your ii should probably run like this:

 for ii = 1:numel(Database)

Also it is not quite clear to me what you want to achieve with your subplots. You seem to have 10 variables in column(2:11) for each of your 3 x 5 models that you try to plot against column(1). That will result in 3 x 5 x 10 = 150 subplots. Is that what you want to achieve?

BTW: It would also be easier to store your Dataabase in a 3x5x 3001x11 matrix. Because all entries have the same size you do not need cell arrays:

 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'];
     Database(i, j,:,:) = xlsread(filename);
   end
 end
