i need a function in matlab to solve trial and error problems such as

Code: 
Φ=atan(x)-atan(1/x)
to find the value of x

thanks alot
 

why dont you just sweep x and see the output in matlab

Click to expand...

i know this solution....but if i don't know the range of x ,it will take long time to know its value
i think there is another method to find it
 

You can try the fzero function.
e.g: a=fzero(Φ-(atan(x)-atan(1/x)),x0); where x0 is a 2 element vector defining the interval at which to search for the solution. You can check its help at mathworks web site:
