Hello,
I'm new and I don't know how to put a set of numbers in one equation
fi = [0 3 13 23 33 34 43 53 63 73 83 90]
My equation:
N = a / (sqrt(1-e2 * sin(fi)^2))^3/2

a = 1; % made up values - replace with the real ones
e2 = 0.1;
fi = [0 3 13 23 33 34 43 53 63 73 83 90];
N = a ./ (sqrt(1-e2 * sin(fi).^2)).^3/2;
% ^ ^ ^--- change these to element-wise operators
plot(fi, N)
grid on
xlabel 'fi'
ylabel 'N'
In case you meant 1e-2 instead of 1-e2:
N2 = a ./ (sqrt(1e-2 * sin(fi).^2)).^3/2;
figure
plot(fi, N2)
grid on
xlabel 'fi'
ylabel 'N2'

As you have not specified the values of a and e2, I am assuming random scalar values for them.
Use array operations - Array vs Matrix Operations
fi = [0 3 13 23 33 34 43 53 63 73 83 90]
%Random value between 0 and 1
a = rand;
e2 = rand;
% vv vv vv
N = a./(sqrt(1-e2 * sin(fi).^2)).^3/2
If e2 is a vector, then use element-wise multiplication for e2 and sin() as well.

Replace
N = a / (sqrt(1-e2 * sin(fi)^2))^3/2
by
N = a ./ (sqrt(1-e2 * sin(fi).^2)).^3/2
For an explanation, I suggest reading
