Hi, I am trying to run a for loop as part of my code. I am trying to have 15 j values between z2 and z1 which are decimal numbers and change with every iteration. The error I am getting is "Subscript indices must either be real positive integers or logicals."I know I am getting the increments wrong but need some suggestions to solve the error.
for i = 1:1:49
X_even = [];
C_even = [];
P_even = [];
z1 = S0 - 2 * std(S) * sqrt(T - dt);
z2 = S0 + 2 * std(S) * sqrt(T - dt);
z = (z2-z1);
for j = z1:(z2-z1)/15:z2
X_even = [X_even ; X1(j,i)];
C_even = [C_even ; C1(j,i)];
P_even = [P_even ; P1(j,i)];
end
X1_even = [X1_even X_even];
C1_even = [C1_even C_even];
P1_even = [P1_even P_even];
end

You need to do something like this:
vj = z1:(z2-z1)/15:z2;
for j = 1:length(vj)
X_even = [X_even ; X1(j,i)];
C_even = [C_even ; C1(j,i)];
P_even = [P_even ; P1(j,i)];
end
If you are using ‘vj’ in calculations (although you do not seem to be in the code you posted), refer to fractional ‘j’ as ‘vj(j)’.

There's no such thing as element 799.9 of an array, like you're trying to assign to in this for loop.
for i=stress0.plus10;1500
strain.stressplus10(i)=(i/E1)+((i-stress0.plus10)/E2); % This is where my error begins
end
The semicolon in the line with your for loop should probably be a colon, but that won't save you because the first iteration through the loop you're trying to assign to strain.stressplus10(799.9).

Als, that should be a new Question. It has nothing directly to do with the current thread.
