Does anyone know why I keep on getting an unexpected Matlab error in this program. It says it occurs in line for (%the original equation) and I think it has something to do with a coefficient to x? I don't know, I have ran this program before with a different equation and it works. ANy help would be greatly appreciated and suggestions on the fix...
x=input('Type the number 32 for your intial guess:')
x=((x-32)*5/9)+273.15
y=-5.6703*e-8x^4-2x+548.30 %orginal equation
while abs(y)>.0001
a=x+.0001 %find derv 1
ya=-5.6703*e-8a^4-2a+548.30
b=x-.0001 %find derv 2
yb=-5.6703*e-8b^4-2b+548.30
dydx=(ya-yb)/(a-b) %derv
z=dydx*a-ya
x=z/dydx
y=-5.6703*e-8x^4-2x+548.30
end
