operator > is not supported for operands type of cell

I load mnist data set in matlab, and i load the weights that i got it from tensor flow and i want to implement this equations to get gex, gin , but when i try that this error shown " operator > is not supported for operands type of cell "

load(' w.mat ')
Rmin = 1e5
Rmax = 1e6
Gmin = 1.0/Rmax
Gmax = 1.0/Rmin
if (w >= 0)
    gex = Gmax*w + Gmin*(1-w)
    gin = Gmin
else
    gex = Gmin
    gin = -Gmax*w + Gmin*(1+w)
end

This is the weights as shown in the screenshot (1*4 cell)

None of the relational operators are defined for cell arrays. A cell array can contain basically any type of data you can create in MATLAB. In the example below, if > were defined for cell arrays what would you expect y to be?

c = {-5:5, magic(4)-3, @sin, {42}, "abracadabra"}

c = 1×5 cell array
    {[-5 -4 -3 -2 -1 0 1 2 3 4 5]}    {4×4 double}    {@sin}    {1×1 cell}    {["abracadabra"]}

% y = c > 0

While > is not defined for cell arrays it can be defined for the types inside a cell. Index into the cell with curly braces to extract the data stored inside it then use > on that data.

y2 = c{1} > 0

y2 = 1×11 logical array
   0   0   0   0   0   0   1   1   1   1   1
