Subscript assignment mismatch.

Hi.

I run my code, and get this response:

d =[ 0    0.9539    1.0584    1.1880    0.4512
  0.9539         0    0.8293    1.1050    1.0646
  1.0584    0.8293         0    0.4785    0.7907
  1.1880    1.1050    0.4785         0    0.8752
  0.4512    1.0646    0.7907    0.8752         0]

Subscripted assignment dimension mismatch.

Error in geomp (line 105)
  d(w,w) = [];

>>

The for loop is as follows:

d
for w=1:5 
 d(w,w) = []; 
end

and as you can se, it displays d, but it is not deleting d(1,1), d(2,2) etc.

I have run ismatrix(d) (and gotten 1) as well as size(d), which is 5 5

Whats going on here?

If you delete d(1,1) what is the expected result? You can't do it unless d is a cell array

For example:

d=[1 2 3;4 5 6]

If you delete the first element

d(1,1)=[];

What are you expecting as result? is it a matrix? what kind of matrix that rows are not the same size! You can define a cell array

d={1 2 3;4 5 6}
d(1,1)={[]}

I would expect a new matrix with one row less.

If you want to delete any row:

A=[1 2 3;4 5 6;7 8 9]
idx=2   % the second row to delete
A(idx,:)=[]

If you want to delete the third column:

A=[1 2 3;4 5 6;7 8 9]
idx=3   % the third  column to delete
A(:,idx)=[]
