If you just want to make a vector out of it, use the ‘(:)’ notation:
A = rand(83,6580);
V = A(:);
‘V’ is a (546140x1) double.

"To make V as 1D array"
Unlike some languages MATLAB does not have any concept of 1D arrays: all arrays have atleast 2 explicit dimensions and infinite implicit trailing singleton dimensions. Because the first dimension is the row dimension the most "basic" kind of vector is actually a column vector.

Alright I also want to add a precaution here while using it, It operates in column wise concatenation.

To Convert a 2D Matrix into a 1D Array( i.e a row vector), such that row vector is formed by concatenating consecutive rows of the 2D Matrix, use the following Code :
OneDArray = reshape(TwoDArray',[1 size(TwoDArray,1)*size(TwoDArray,2)]);

OneDArray = reshape(TwoDArray.',1,[]);
