Hi. I have a cell 30x1 and each cell has 4 columns and 1 row. I want to assign the row values from 4 columns to 4 variables using a for loop. I tried using
for i = range(1:30)
for j = range(1:4)
Y = P{i,1}(1,j);
A = P{i,1}(1,2);
B = P{i,1}(1,3);
C = P{i,1}(1,4);
end
end
but I only assigned the last value form the last cell to the variable. Can someone help me where am i making an error?

Y, A, B, and C get overwritten on every single iteration.
Why not simply use cell2mat(P)?

so i should use the for loop after the applying cell2mat to the cell? Because i need to assign values from all rows and each column to single variable.

How are you combining a bunch of numbers into a single number? Summing them? Taking their mean? Please give a small example.
