MATLAB: How to convert 21 cell array into 12char array

cell arrayscharcharacter arrayconvertstring

    egr = Tier'       % egr returns 'T2' 'S2'  as 1*2 CELL
    sgr = char(egr);  % sgr returns  T2
                                     S2  as 2*2 char

My desired output should look like 'T2' 'S2' or 'T2','S2' in char

Best Answer

   egr = {'T2' 'S2'};
   sgr = ['''', strjoin(egr, ''' '''), ''''];
   disp(sgr)

This will display as

'T2' 'S2'

which is to say that sgr will be a character vector that contains those literal characters, which appears to be what you are asking for.

However, this appears to have nothing to do with your switch statement, since you have

    switch (T3)

and T3 has nothing to do with egr or sgr.

MATLAB: Accessing the index of a matrix element inside the cell array

First, a few recommendations.

If you're using vectors use linear indexing instead of 2D indexing. I.e. X{1} instead of X{1, 1}.
if n<=3 ... elseif n>3 ... end, if the if is false you're guaranteed that the elseif is true. Therefore the elseif is not needed, you can simply write if n<=3 ... else ... end. In general, you should always finish by an else, not an elseif.
don't use the same variable name, particularly one as meaningless as c for storing to different things. In your code, c is used to store the index where plotnumber is found in the cell array, then to store plotnumber.
Whenever you end writing the same lines of code with only small variations between them it's a clear indication that there must be a better way, such as indexing.

In particular, with that last point, we can rewrite your code as:

[f,T1, X] = Samplemodel_Instat('Measuring_Data.mat');
% X will be like this X = {[ 2 4] [ 'Oil'  'Air']};
%Now defines the constants that will be used for plots, as 5xN matrices (as there are 5 different possible plots)
Colours = [0.831372559070587 0.815686285495758 0.7843137383461;
           0.25 0.25 0.25;
           0.952941179275513 0.87058824300766 0.733333349227905;
           0.31 0.31 0.31;
           0.831372559070587 0.815686285495758 0.7843137383461];
LineWidths = [0.5; 4; 2; 2; 0.5];  %0.5 is default for plot
LineStyles = {'-'; '-.'; '-'; '-'; '-'};  %'-' is default for plot
Markers = {'none'; 'none'; 's'; 'none'; 'none'};  %'none' is default for plit
for plotnumber = 1:n
    whichmodel = find(X{1} == plotnumber,1);
    if ~isempty(whichmodel)
        if n <= 3
            plotstyle = 1;   %which row of Colours, LineWidths, etc.. to use
        else
            plotstyle = discretize(plotnumber, ceil((0:4)*n/4), 'IncludeEdge', 'right') + 1;
        end
        if ismember(plotstyle, [1 3])
            plotindices = (1:150:numel(f)) / 3600;
        else
            plotindices = (1:200:numel(f)) / 3600;
        end
        plot(f(indices), T1(plotnumber, indices), ...
             'Color', Colours(plotstyle, :), ...
             'LineWidth', LineWidths(plotstyle), ...
             'LineStyle', LineStyle{plotstyle}, ...
             'Marker', Markers{plotstule}, ...
             'MarkerFaceColor', [1 1 1]);
        legend(X{2}(whichmodel));  %index 2nd element of cell array
    end
end
