Dear community,
I have a cell
A=cell(m,n)
and a logical vector
b=(m,1)
containing logical ones and zeros (true, false). What I like to do now is to delete the cell entries, if there is a logical one
A(b,:)=[];
But the error is: Index of element to remove exceeds matrix dimensions. What have I done wrong?
Thanks a lot!

n=3;
m=6;
A=num2cell(rand(m,n))
idx=[1 0 0 1 1 0]
A(logical(idx),:)=[]

Hi!
Are you sure that b is not longer than size(1) of A? Is b really a logical vector with true or false? I have no problem if I use
n=3
m=5
A=cell(m,n)
b=false(m,1)
b(2) = true
b(5) = true
A(b,:)=[]
An error is thrown for
A=cell(m,n)
b(6) = true
A(b,:)=[]

Thanks for your answers, I still have the error code:
Index of element to remove exceeds
matrix dimensions.
I checked the sizes now for 100 times :D I don't know what could help me, m is always the same.

I'm wondering where your error message comes from. If I use my example above the message is
Matrix index is out of range for deletion.
Tested on Matlab R2010b. Maybe we use different versions or the problem is different ...
