Using 'fzero' in a for loop
显示 更早的评论
Hello,
I am trying to solve for the roots within a 'for loop', and within the function for which I am root finding, I am using a previously defined variable.
It might make it easier to show my code:
A_Astar_x = zeros(1,IL-1);
Mach_Test = zeros(1,IL-1);
M_x = zeros(1,IL-1);
for i=1:IL-1
A_Astar_x(i) = (y(i,JL)-y(i,1))/(y(1,JL)-y(1,1))*A_A;
Mach_Test(i) = @(set) A_Astar_x(i)-(1/set)*((1+.5*(gamma-1)*set^2)/(.5*(gamma+1))).^alpha;
M_x(i) = fzero(Mach_Test(i),.2);
end
I get an error message that says:
Conversion to double from function_handle is not possible.
Does this error message mean that I cannot solve for the roots iteratively like this?
If not, does anyone know any other methods to go about this?
Thanks,
Jon

Do you really need to save the sequences of anything besides the M_x(i)? If not, then,
for i=1:IL-1
A_Astar_x = (y(i,JL)-y(i,1))/(y(1,JL)-y(1,1))*A_A;
Mach_Test = @(set) A_Astar_x-(1/set)*((1+.5*(gamma-1)*set^2)/(.5*(gamma+1))).^alpha;
M_x(i) = fzero(Mach_Test,.2);
end
