Question

If I have a matrix

A = [0 1 0 1
     0 0 1 1]

and a variable B = 121.23,
how can I concat both into a one variable.

I did

features_set = [A(:), B];

But, it gives an error CAT arguments dimensions are not consistent.

How can I add this variable B to the end of the vector A?

Answer 1

A(:) returns an 8-by-1 array. The comma appends along the second dimension. Thus, your code fails.

If the output should be a 9-by-1 array, you should write

features_set = [A(:);B];

If the output should be a 1-by-9 array, you should write

features_set = [A(:)',B];
