Hello,
Can anybody help me, cant understand why do i get this error when i run it?
I have an error that is Error using vertcat
Dimensions of arrays being concatenated are not consistent.
VariableLocations = ([COL; HPPC_Output.Properties.VariableNames; ...
the code is written below:
% Re-arrange variable locations
VariableLocations = ([COL; HPPC_Output.Properties.VariableNames; ...
num2cell([3:14 22 36 28 33 16:19 24 23 25 20 21 15 1 30 29 27 32 26 31 34 35 37 2])])'; % Manually input location of variables wrt COL - future work includes automating this
VariableLocations = cell2table(VariableLocations); % Convert to table
VariableLocations = sortrows(VariableLocations, 3, "Ascend"); % Sort so numbers are ascending
for i = 1:height(VariableLocations)
HPPC_Output = movevars(HPPC_Output, VariableLocations{i,2}, 'After', width(HPPC_Output)); % Move each variable to the...
% end of the table until they are in order
end
% Finalise UIC
for i = 1:height(HPPC_Output)
j = num2str(i); % Convert row number, i, to a string
HPPC_Output.UIC(i,:) = append(HPPC_Output.UIC(i,:), j); % Append string to the end of UIC
end
line 419 is VariableLocations = ([COL; HPPC_Output.Properties.VariableNames; ...
Dimensions of arrays being concatenated are not consistent. " is written near line 419.
Thank you for support.

Either COL and/or HPPC_Output.Properties.VariableNames do not have 37 columns.

Hi Tugce,
To concatenate A and B vertically, all dimensions except the first must be the same. For example, consider the following case,
A = zeros(2,3); % 2x3 matrix
B = zeros(5,3); % 5x3 matrix
% A and B can be concatenated vertically
C = [A;B];
disp(size(C))
B = zeros(5,4); % Now B is 5x4 matrix
% A and B cannot be concatenated vertically since the second dimension is
% not matching
C = [A;B];
The error has occurred while executing the following line. To resolve the error, print the dimensions of 'COL' and 'HPPC_Output.Properties.VariableNames' and verify whether they are matching or not.
VariableLocations = ([COL; HPPC_Output.Properties.VariableNames; ...
num2cell([3:14 22 36 28 33 16:19 24 23 25 20 21 15 1 30 29 27 32 26 31 34 35 37 2])])';
% Manually input location of variables wrt COL - future work includes automating this
Hope this is helpful.
