i want to convert a cell array having different number of rows into a matrix. I tried different ways but couldnt get the exact solution

for j1=1:m1
    [pks{j1},fa{j1}] = findpeaks(z1(1:end,j1));
    [pks1{j1},fr{j1}] = findpeaks(-z1(1:end,j1));
end

Do you mean different number of columns?

You can not concatenate rows/columns having inconsistent dimensions to obtain a numeric matrix.

y={[1 2];[3 4 5]};
cat(1,y{:})
Error using cat
Dimensions of arrays being concatenated are not consistent.

You might have to pad the rows/columns with NaN or any other value.
