I am trying to change a matrix located in my workspace. It is originally a 1 x 48 matrix and I am just wondering how to edit the dimensions of the matrix. Thank you!
Attached below is my code:
data = textscan(fileID, '%f%f%f%f%f%f','HeaderLines',6,'CollectOutput','');
fclose(fileID);
X = data{1};

doc reshape
E.g.,
X = your 1x48 vector
Y = reshape(X,4,12); % <-- reshaped to a 4x12 matrix
Z = Y(:); % <-- reshaped to a column vector

If you want to change the shape of the array without changing the number of elements, take a look at the reshape function.
If you want to change the number of elements in the array, you'll probably want to use the repmat or repelem functions or the operations of indexing or concatenation.
