Hey all.

I asked this question already, But I didn't get the solution I intended.

I have a cell array

A = { [ 2 4 6] ['Air'; 'oil'; 'Metal']}

Here I am putting a part of my code.

for count = 1:n
if whichnode = find(X{1} == count, 1)
if ~isempty(whichnode)
whichnode = count;
% here I need to find the indicies of the count, which(number) will be there in matrix of the cell A{1}, I know using this, for an example if count = 4, it's indicies is A{1}(1,2). %This I can write manually, but I can't write it for each input. So I need to find the indicies for any input in A{1} again. One more example, if count = 9, it's indicies should be given automatically before the plot function.
plot(f, T1, 'DisplayName', A{2})
end
end
end

Here my Idea is to get the indices of the count in the matrix of the cell array, before the solver enter the built in function plot.

The reason is, using that indicies, I can display the name of the plot easily with my idea.

I don't know whether it is possible or not!. But If we get the idea, there should be a way to do it. I need that way.

Any suggestions and answered are most welcomed!

Thanks in advance

@Stephen Cobeldick

[f,T1] = Samplemodel_Instat('Measuring_Data.mat');

[Lambda, A, B, D,V,H, Rho,cP,P, M, A1,O, X, M_1] = Matrix_Samplemodel;

A = { [ 2 4 6] ['Air '; 'oil '; 'Metal']}

or X = {[ 2 4 6] [ 'Node2'; 'Node4' ; 'Node6']}

figure('Color',[1 1 1])

for plotnumber = 1:n

whichnode = find(X{1} == plotnumber,1);

if ~isempty(whichnode)

% Here I need to find the indicies of the plotnumber, which(number) will be there in matrix of the cell A{1}, I know using this, for an example if count = 4, it's indicies is A{1}(1,2). %This I can write manually, but I can't write it for each input. So I need to find the indicies for any input in A{1} again. One more example, if plotnumber = 9, it's indicies should be given automatically before the plot function.

%plot(f(1:200:end)/3600,T1(plotnumber,1:200:end),'Color',[0.25 0.25 0.25],'LineWidth',4,'LineStyle','-.','MarkerFaceColor',[1 1 1],'Marker','none','DisplayName', X{2} );

end

Actual data it too big to paste here and also difficult to give the explanation to everything.

Thank you, I didn't notice the error intially.

I think now it is correct to get the solution.

Thanks in advance

@ Jan & Guillaume

Thank you for all your kind responses.

I found the answer by myself. one of your colleague gave me the hint on the other day. Now I remembered that. Finaaly I did it.

'How is this any different from your previous question for which you accepted my answer?'

Th difference is I need the specific name Like X{2} = ['Air'; 'Oil';' Material']. But vector dimensions is not correct. I just need to know how to fix it!

Below was my code with the help of Bob.

@surendra kumar Aralapura mariyappa: X{2} = ['Air'; 'Oil';' Material'] is no valid Matlab syntax and this has been mentioned repeatedly already. You do not mention, what you want to achieve but repeat to post this strange piece of code. So how can we help you?

Maybe you want this instead:

X{1} = {'Air'; 'Oil';' Material'}
%      ^                        ^ Curly braces, not square brackets

X{1} = ["Air"; "Oil";" Material"]
%       ^   ^  ^   ^ ^         ^  double quotes for strings
