Error using vertcat Dimensions of arrays being concatenated are not consistent

40 views (last 30 days)
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; ...
Also, "Error using vertcat
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))
7 3
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];
Error using vertcat
Dimensions of arrays being concatenated are not consistent.
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.
