Solving an equation multiple times using a for loop
显示 更早的评论
Hello,
I am trying to solve the following equation for time (t) using different air temperatures. Matlab says that the solution is 0*1 empty double column vector!
Thank you for your help.
clear all
clc
x=1
for T_a_amb=[270.928:0.01:272.594] %ambient air temperature
syms t
a = -4/(T_a_amb-277);
b = 5.948e-5;
c = 0.00771;
eqn = 1-(exp(b*t)*(1-erf(c*sqrt(t)))) - a== 0; %
solution = double(vpasolve(eqn,t,[0,1]))
solmate(x,1) = T_a_amb;
solmat(x,2) = solution;
x = x+1
end

Is the vpasolve coming up with a set of answers? That would be my first thought to check.
