pts3 = H*[pts1;ones(1,n)];

Error using * Inner matrix dimensions must agree. Here H is array but I do not understand the meaning of [pts1;ones(1,n)] can any one guide me what does it mean.

and as per matrix multiplication m1[r1,c1] and m2 [r2,c2] then c1 and r2 must match otherwise error should get generated otherwise continue matrix multiplication I want to add this line please help me in it.

Thank you in advance

[r1,c1] = size(m1) ;
[r2,c2] = size(m2) ;

if c1~=c2
    error('m1 and m2 cannot be multiplied')
else
    fprintf('m1 and m2 can be multiplied\n')
end
m12 = m1*m2 ;

[KSSV]

   [pts1;ones(1,n)]

In the above line two different arrays are joined/ concatenated. pts1 is one array and ones(1,n) is an array which has n 1's.
