Error using round every time can anyone please help me with this?

c= 1;
n = 0.025;
bw = 36;
angle = 60;
syms x
tw = simplify(bw + 2*(x * tand(angle)));
A = 0.5*(bw + simplify(tw))*x;
            P = simplify(bw + 4*x);
            %%2* simplify(sqrt((x^2)+((x*tand(angle))^2)))
            S = 0.00001;
             
       
Q = 347.9;
syms brand height
                brand = ((c/n)*((A^1.666)/(P^0.666))*(S^0.5)) == Q
                height = vpasolve(brand, x)
             stage  = round(height,4); %%%LINE 18%%

ITS SHOWING TOO MANY INPUT ARGUMENT WHY SO?

OUTPUT

Error using sym/round

Too many input arguments.

Error in Untitled2 (line 18)

stage = round(height,4)

Answer 1

Convert ‘height’ to double first:

stage  = round(double(height),4) %%%LINE 18%%

The round function for symbolic expressions does not accept the input argument N (the number of digits to which to round) like the round function for numeric arrays does. If you convert your height variable to double then you can call round to round the number to 4 places.

thanks steven.
