I want to remove all zeros from cells a matrix, so i can use it in a for-loop later on. The structure of the matrix should not change after the zeros are removed. So every row should stay the same, just without the zeros in the cells. Right now the size of my matrix is 27895...
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...
댓글:PetterE2020년 9월 8일 채택된 답변:Andrei Bobrov Hi I am still fairly new to matlab and not very familiar with it yet. I was wondering how I could remove zeros from the beginning of my matrix. i.e. A = [0 0 0 1 2 3 0 4 5] and removing the first zer...
How do I delete all the columns that have zeros with a for loop? I tried reducing the number of columns by one in every iteration but matlab shows me "index exceeds matrix dimentions". p4 = [0 0 31 37 43 47; 0 0 19 13 7 3]; grammes = size(p3,1); sthles = size(p3,2);...
