I'm trying to calculate the kernel coefficient for volume scattering by inputting a range of values for t1r and g into my kvol variable.
how would i create a matrix for kvol that is in terms of my other matrices, t1r and g?

Ran in:
t0 = 0.5235;
t1d = 0:60;
t1r = deg2rad(t1d);% use this function to convert to radians
phi = pi;
g = cos(t0)*cos(t1r) + sin(t0)*sin(t1r)*cos(phi)
g = 1×61
0.8661 0.8572 0.8481 0.8387 0.8291 0.8192 0.8091 0.7987 0.7881 0.7772 0.7661 0.7548 0.7432 0.7314 0.7194 0.7072 0.6947 0.6821 0.6692 0.6561 0.6429 0.6294 0.6157 0.6019 0.5879 0.5737 0.5593 0.5447 0.5300 0.5151
kvol = ((0.5*pi-g).*cos(g)+sin(g))./(cos(t0)+cos(t1r)) - (pi/4)
kvol = 1×61
-0.1325 -0.1299 -0.1271 -0.1241 -0.1209 -0.1175 -0.1139 -0.1101 -0.1061 -0.1019 -0.0975 -0.0929 -0.0881 -0.0831 -0.0778 -0.0724 -0.0668 -0.0609 -0.0549 -0.0486 -0.0421 -0.0354 -0.0286 -0.0215 -0.0142 -0.0067 0.0010 0.0090 0.0171 0.0254

Use
kvol = (((0.5*pi-g).*cos(g)+sin(g))./(cos(t0)+cos(t1r))) - pi/4
instead of
kvol = (((0.5*pi-g)*cos(g)+sin(g))/(cos(t0)+cos(t1r))) - (pi/4)
