problem conversion to char from logical why?

ello

can somebody help me solve this?

my code so far:

clc;
clear all;
syms x y;
eqn=((x*sqrt(x)-y*sqrt(y))/(sqrt(x)-sqrt(y))+sqrt(x*y)*((sqrt(x)-sqrt(y))/(x-y))^2) == 0;
solx=solve(eqn,x)
soly=solve(eqn,y)

thanks

@Jan Bozic: I edited your question to correctly insert the image and format your code. Next time you can do it yourself by using the buttons along the top of the textbox (do not write HTML code in the text).

You are using MATLAB before R2010b (or was it R2011b?)

Replace

eqn=((x*sqrt(x)-y*sqrt(y))/(sqrt(x)-sqrt(y))+sqrt(x*y)*((sqrt(x)-sqrt(y))/(x-y))^2) == 0;

with

eqn = ((x*sqrt(x)-y*sqrt(y)) / (sqrt(x)-sqrt(y)) + sqrt(x*y)*((sqrt(x)-sqrt(y)) / (x-y))^2) - 0;

The spacing only affects the readability but changing the "== 0" to "- 0" should fix the conversion problem.

hi, thanks for fast answer, i'm using 2010a version.
