MATLAB: Sub indexing into cells

indexing cells

Hello,

I am wondering if anyone can give me any pointers on a topic.

I have a logical vector of true false the same number of rows as my raw matrix.

The raw matrix, I would like to index for the rows that that are true in my logical vector.

The raw matrix is in cell format though and is a big mash of numerical and written data so I can't seem to convert it to another form.

Is there a way for me to pull the rows i'm interested in from this matrix?

Thanks for any help/advice/direction

"Is there a way to determine their indices using logical indexing...?"

Yes, and logical indexing is usually a better way to index than using a linear index or subscripts, and you've already discovered how to do it :)

logicalIndex = iList & ~rList & ~dList;

" I've had trouble wrapping my head around how I might achieve that."

Here's a general demo

data = rand(5,10);  % random values between 0 and 1
idx = data <0.5;    % logical index of values less than 0.5
data(idx) = NaN;    % Replaces values < 0.5 with NaNs
