How to add zeroes to a matrix to make the dimensions same.

I am not able to convey my problem. My code is really long hence i am not able to upload it. could you tell me this my matrix dimensions are A= 335 by 16 B=314 by 1 How can i add zeroes to make B= 335 by 16

MY code is this function d = disteu(x, y) % DISTEU Pairwise Euclidean distances between columns of two matrices % % Input: % x, y: Two matrices whose each column is an a vector data. % % Output: % d: Element d(i,j) will be the Euclidean distance between two % column vectors X(:,i) and Y(:,j) % % Note: % The Euclidean distance D between two vectors X and Y is: % D = sum((x-y).^2).^0.5

 %  D = sum((x-y).^2).^0.5
 [M, N] = size(x)
[M2, P] = size(y)

if (M ~= M2)

error('Matrix dimensions do not match.') end

d = zeros(N, P);

if (N < P) copies = zeros(1,P); for n = 1:N d(n,:) = sum((x(:, n+copies) - y) .^2, 1); end else copies = zeros(1,N); for p = 1:P d(:,p) = sum((x - y(:, p+copies)) .^2, 1)'; end end

d = d.^0.5;

I want to remove the error "matrix dimensions do not match"

@Bisma Waheed: Please do not ignore the already given advice to format your code, see Tutorial: Format code . It is in your interest, that your code can be read without difficulties. The process is trivial: Mark the code with the mouse and press the "{} Code" button. Thank you.

You mention "A" and "B" in the question, but it is not clear, which variables in the code you mean. I do not think that filling a matrix with zeros helps to calculate the Pairwise Euclidean Distances.

Answer 1

[Stephen23]

B(335,16) = 0;

will automatically expand the matrix B to have size 335x16, the added elements have the default value (zero). Note that you will need to add code to check if B already has enough rows.

The question contains the code comment "Pairwise Euclidean distances between columns of two matrices", but it is not clear how inventing data helps this calculation.
