Adding values to a table from an if statement

I'm performing a sequential Gaussian analysis and am trying to populate a table using an if statement. I keep getting an error saying that dot indexing is not supported for varialbes of this type for this section of code. Basically, I have preset a table with zeros, and then the code checks against another table X if the value is smaller or larger than the min and max defined. I want the code to assess the if statement and then populate the table Z with 0 or 1 in the column specified. Thanks!

X = [157.5:315:31342.5];

Z = zeros(100,11);

maxnum = max(T.Var2);

minnum = min(T.Var2);

for a = 1:100

if X{a,1} > minnum & X{a,1} < maxnum

Z.Var1{a} = 1;

else

Z.Var1{a} = 0;

end

end

X = (157.5:315:31342.5).';
Z = table();
maxnum = max(T.Var2);
minnum = min(T.Var2);
Z.Var1 = minnum < X & X < maxnum;

Z is not a table. It is a 100x11 matrix of zeros. Therefore, you would use normal indexing (row, column) to assign values to it.

Also, you do not need the for loop. Create a logical array instead, and assign that to the desired column (see ch 12 of MATLAB Onramp).

I've made your matrix smaller for demontration purposes.

X = 1:10;
Z = zeros(10,2);
maxnum = 8;
minnum = 5;

V = X>minnum & X<maxnum

V = 1×10 logical array
   0   0   0   0   0   1   1   0   0   0

Z(:,1) = V

Z = 10×2

0 0 0 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 0 0

Also, X is not a cell array, so X{a,1} wasn't going to work, you needed X(a,1). In any case, Wlater's non-loop sol'n is the way to go.
