read csv file in sequence and post process data

Hello all,

I have written a code manually to extract information regarding 5 matrices and postporcess the data (I want to get the maximun value of the column 11, . Each matrix has a different size (12 columns x around 300 rows).

The example of this code is:

T1 =csvread('contour_oh01_pe100.1.csv',1,0);

T2 =csvread('contour_oh01_pe100.2.csv',1,0);

T3 =csvread('contour_oh01_pe100.3.csv',1,0);

T4 =csvread('contour_oh01_pe100.4.csv',1,0);

T5 =csvread('contour_oh01_pe100.5.csv',1,0);

[M1,I1] = max(T1(:,11))

row1=T1(I1,:);

[M2,I2] = max(T2(:,11))

row2=T2(I2,:);

[M3,I3] = max(T3(:,11))

row3=T3(I3,:);

[M4,I4] = max(T4(:,11))

row4=T4(I4,:);

[M5,I5] = max(T5(:,11))

row5=T5(I5,:);

I am try to do it using a for-loop. But I am having problems to store the T1,T2,T3, T4 and T5:

for i=1:5

T(i)=[T,'num2str(n)']

[M(i),I(i)]=max(T(i)(:,11))

end

I hope that you may help me.

Use cell arrays instead of numbering variables ( https://www.mathworks.com/matlabcentral/answers/105936-how-to-make-dynamic-variable-names-a1-a2-an-with-for-loop-using-eval-num2str ):

T=cell(1,5); % preallocate
row=cell(1,5);
M=cell(1,5);
I=cell(1,5);
for k=1:5
T{k}=csvread(sprintf('contour_oh01_pe100.%d.csv',k),1,0);
[M{k},I{k}] = max(T{k}(:,11));
row{k}=T{k}(I{k},:);
end
