Hi everyone,
I want to solve this equation in Matlab. Until now I have the following code:
syms x
I get next error: Check for missing argument or incorrect argument data type in call to function 'solve'.
Error in Untitled (line 8)
I dont know what it is wrong, can anybody help me?
Any help is appriciated.

i have also this error
with this function
[V1,V2,V3]=solve('(V1-V2)/R1 = Is + 2*(V3-V2)/R3','(V2 - V1)/R1 + V2/R2 + (V2-V3)/R3 = 0','(V3-V2)/R3 + V3/R4 + 2*(V3-V2)/R3=0','V1','V2','V3')

You're missing double equals sign in your equations.

syms x
eqn = cos(x).*(a.*sin(x)+b) == c

The sintax is correct here but it is of no help to find the solution, because there is no real-type one, and "solve" refuses working with the complex type. To find the solution you should reformulate the problem as a system of two real-type equations for the real and imaginary parts being two unknown variables.
