How to delete the row from cell array?

I have a cell arraywhich has 10*6 matrix in it. How can I delete a row from the matrix? thanks in advance.

Answer 1

Is this what you want:

>> A(1:2)={rand(10,6)}

A = 

      [10x6 double]    [10x6 double]

>> row=2; A{1}(2,:)=[]  %delete 1 row from 1 cell

A = 

      [9x6 double]    [10x6 double]

exactly..thanks a lot !!

@matt J how to delete a each matrix with certian cell number. for example, cell matrix is [999*1][999*1][989*1][999*1][999*1]...[998*1]. Now from each cell matrix, i want to delete from 800 to end of cell matrix. how can i do that?

I tried cell{:,1}(801:end,1) = []; but getting error as A null assignment can have only one non-colon index. thanks in advance

@Ram: you will have to use a loop.

[Matt J]

As Stephen says, you will have to use a loop, but you can also hide the loop with cellfun,

cellfun(@(c) c(1:800), yourCell, 'uni',0 )

row=2
A(row,:)=[]

suppose i have 1*3 cell as shown above and A is a matrix of dimensions 3*3 and I want to delete second row of the A matrix. How should i do it?

Will it be

A(1,1)(2,:) = []

[Azzi Abdelmalek]

 row=2;
out=cellfun(@(x) x(setdiff(1:10,row),:),A,'un',0)

You can index out the rows like any standard array (the following code removes the second row):

   x = {1 2 3; 4 5 6; 7 8 9}
   x = 

    [1]    [2]    [3]
    [4]    [5]    [6]
    [7]    [8]    [9]

   y = x([1 3],:)
   y = 

    [1]    [2]    [3]
    [7]    [8]    [9]

This will delete row of matrix in a cell. I have many elements in each matrix (in this case theres only one element) I want to delete a row from those matrices.

[John]

Ok I think I understand, you have a cell array that looks like the following:

    A = {rand(5), 1}
    A = 

    [5x5 double]    [1]

You want to remove a row from the matrix in the first element of A. You can do the following:

    A{1} = A{1}([1 2 4 5],1);

(this will remove the third row). Alternatively you can use Azzi Abdelmalek's method shown below:

    A{1}(3,:) = []

I think this is what you are looking for.
