I want Xn to be the sum of all elements in o_vector matrix. In Matlab 2018 and newer versions the

Xn = sum(o_vector,'all');

does this work. But octave doesn't support this. How can I do this in octave?

Hi

Please help me with this error:

operator +: nonconformant arguments (op1 is 1x17, op2 is 1x18)
error: called from
    Project2 at line 14 column 23

The part of the code is:

o_vector(i,j) = input('Please enter the '+num2str(j)+...
            'th element of the '+i+'th region output vector: ');

Also if i bypass this error I have another errors, for example in this line:

Xn = sum(o_vector,'all');

The debuger says "all" is undefined.

Please help me how can I correct these types of errors when using octave instead of Matlab.

Thanks

"all" does not appear to be a recognized option for the sum function - see here:

If you just want to concatenate strings, you could do so with

o_vector(i,j) = input( strcat( 'Please enter the ', num2str(j), 'th element of the ', num2str(i), 'th region output vector: ')

Please always CC the mailing list.

What do you want to do with Xn and ovector? We cannot help unless we know what you are trying to achieve.

You can do that with

Xn = sum(sum(o_vector));

or

Xni = sum(o_vector);
Xn = sum(Xni);
