Error: Conversion to double from cell is not possible

Hi! Can you help me to understand why I have this error?

Matrix(5,1)={sum(matchcounts_ab,1) sum(matchcounts_ba,1) sum(matchcounts_AB,1)};

The following error occurred converting from cell to double: Error using double Conversion to double from cell is not possible.

Thanks

Try

x = {sum(matchcounts_ab,1) sum(matchcounts_ba,1) sum(matchcounts_AB,1)}
whos x
whos M

You try to assign a cell to matrix of doubles.

Use

Matrix{5,1} = {sum(matchcounts_ab,1) sum(matchcounts_ba,1) sum(matchcounts_AB,1)};

and change all others assignments to Matrix accordingly.

Most likely the variable Matrix is a numeric array, and you are trying to assign a cell array to one of its elements. This is an error, because you cannot assign a cell array as an element of a numeric array. Basically you are doing this:

num_array(x) = cell_array

You can either assign that cell to another cell array, or else assign numeric values to a numeric array.
