So I just would like to obtain another matrix but with some indexs (or elements ) and the rest is zeros So I need the output matrix to be 테마복사 O=[ 1 2 0 0 ;2 1 0 0 ;0 0 6 8;0 0 8 16] So can anyone advise me with the best way ? Thanks, 댓글 수...
s-matrixThe dynamical assumption of a minimum of S -matrix zeros is applied to neutral pseudoscalar and symmetric scalar meson theories in the static limit and one-meson approximation. In both models the generality in the S -matrix solutions is reduced to a one-parameter class with an upper ...
if you ant back a 120x120 matrix, just reshape my_cov = reshape(my_cov,L,L); the problem is that the vector my_cov keeps containing all zeros so the overwriting doesn't work. I have a tensor (L, L, H) ppa (where Area is L* L, and the height H is the number of time st...

Been trying to remove these zeros using NaN and find etc. but to no avail. Trying to remove zeros so that I can pull out the end (non-zero) values from each row and put into a new n:1 matrix. If there is also a way of doing this without nessisarily having to remove the zeros...
