Hello everyone,
I have a probelm with euclidean distance. I have a matrix A[30x4800] and vector B[1x4800]. I have count euclidean distance beetwen all rows of matrix A and vector B. In result i should get vector C[30x1] (i guess). I tried this
C=sqrt(sum((A-B).^2));
but i gave me C[1x4800]
Do you have any idea what is wrong?
Thank you in advance!

A = rand(30,4800);
B = rand(1,4800);
C = sqrt(sum((A-B).^2,2))
C = 30×1
