Can I set the initial value of the solution in "solve" function? Like "fsolve" function?
My code is:
syms p z
b=150;beta=10;s=10;s0=5;alpha=0.5;c1=30;cv=10;N=150;
f2=@(x)((x-z).*normpdf(x,10,40));
eqns=[p-(b+beta.*(s-s0)+10+alpha.*c1)./(2.*alpha)+(int(@(x) f2(x),z,N))./(2.*alpha)==0,p-c1-(p-cv).*cdf('Normal',z,10,40)==0];
S=solve(eqns,[p,z]);
S.p
S.z
The result is [p z]=[30,-185], but I know that there exists the other solution [223, 63].
In order to find the latter solution, can I set the initial value of the solution in "solve" function? Like "fsolve" function? If the answer is yes,how?
Thank you very much!

The vpasolve function allows initial estimates and ranges, See: Find Multiple Solutions by Specifying Initial Guesses and related sections for more information.
