MATLAB: How to write this equation

equation

Can someone help me write this equation. I am having problems with a bracket somewhere.Not getting the answer i needed.

Thanks

Best Answer

I used y and B to make it easier to read:

num = 2*y*(r^((y-1)/y)-1)
den = (y-1)*(B^4 - r^(-2/y))
out = sqrt(num/den)

This will get you two real values for ‘r_CFV’:

gama = 1.399;
beta = 0.675;
f = @(rcfv) rcfv.^(1-gama)/gama + ((gama-1)/2)*beta.^4 * rcfv.^(2/gama) - (gama+1)/2;
r_cfv(1) = fzero(f,  1)
r_cfv(2) = fzero(f, 10)
x = linspace(-20, 20);
figure(1)
plot(x, f(x))
grid

Use the Optimization Toolbox fsolve function with real and complex initial estimates to get complex values. Another option is the Symbolic Math Toolbox solve function.

N = 96;
G = 0.072;
alpha = 0.000203;
rho = 0.001095;
k = 0.01438;
Th = 323;
[I0, Tc] = ndgrid(1:10, -60:240);
Qc = 2*N*((alpha .* I0 .* Tc) - (0.5 .* I0 .* I0 .* (rho./G)) - (k .* G .* (Th-Tc)));
surf(I0, Tc, Qc, 'edgecolor', 'none')
