Syntax solinit = bvpinit(x,yinit) solinit = bvpinit(sol,[anew bnew]) solinit = bvpinit(___,parameters) Description: solinit = bvpinit(x,yinit) uses the initial mesh x and initial solution guess yinit to form an initial guess of the solution for a boundary value problem. You then can use the initial guess solinit as one of the inputs to bvp4c or bvp5c to solve the boundary value problem. example: x = linspace(0, 5,10)); yinit = zeros (1,7); solinit = bvpinit (x, yinit);
