Hi, all I want to findminimum of a function f[x,a[0]]=x^2+a[0]*x over {x,0,1}, where a[0] is the solution of a differential equation, say {a'[z] = x*z, a[1]==1}. The code is like, FindMinimum[x^2+a[0]*x/.NDSolve[{a'[z]==x*z,a[1]==1},a,{z,0,1}],{x,0,1}] now the problem is that I can run this code in mathematica 4.2, but can't in mathematica 5.0, do anybody know what is the problem? or what should I modify to do this FindMinimum in mathematica 5.0? thanks, Jiang
