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 27895x5

Comments psted as flags by @Moritz Nusser (please don't use flags to post comments, they are meant to attract the attention of site admins):
ok, so which kind of removement would you choose so that the "for-loop" won't create error mistakes ?
Thank your for your fast response ! Is it possible to use cell arrays for calculations in a for loop ?

If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks). That will teach you how to work with cell arrays.

Hi moritz,
If you want to remove zero from a cell then you will have remove that row also otherwise it will not remain a matrix structure.
for removing any row you can do--->
tableName(rowNumber,:)=[ ];
I would suggest you to go through this Matlab Onramp course it just an 2 hours course you will understand everything

Note that column 5 of the image in the question contains all 0s so this proposal would potentially eliminate all of the data.
