Anonymous Function with natural log inside
显示 更早的评论
I am trying to make an anonymous function with a natural log inside. Here is my code:
p = @(h)29.921*(1 - 6.8753*10^-6.*h);
T = @(p)49.161*log(p) + 44.932;
h = -500:14439;
p(h);
T(p);
plot(h,T(p))
When I run it, I get this error:
Undefined function 'log' for input arguments of type 'function_handle'.
Error in Elevation>@(p)49.161*log(p)+44.932
Error in Elevation (line 10)
T(p);
Is it because p is an anonymous function, too? Or is it something else? How can I fix this?

Your functions are actually all functions of ‘h’. To refer to ‘p’ in ‘T’, you need to refer to it as ‘p(h)’.
This works:
p = @(h)29.921*(1 - 6.8753E-6.*h);
T = @(h)49.161*log(p(h)) + 44.932;
h = -500:14439;
p(h);
T(h);
plot(h,T(h))
