## Heat equation in 1 dimention - help needed...

I enclose Maple general solution to the PDF heat equation in 1 dimention.

I need corrections of it to enable me to calculate the heat equation in certain conditions :

du(x,t)/dt - d^2/x,t)/dx^2 = ;   t>0, x belongs to interval [0,phi[

with boundary conditions :

u(x,0) = sin(x)cos^2(x) ; x belongs to interval [0, phi)

u(0,t) = 0

u(phi,t) = 0  ;  t is still t>0

## Fsolve and initial parameter values...

Hi,

I'm solving a non-linear system of equations (8 equations, 7 parameters) numerically using Fsolve.

Here's my problem: I run fsolve in a loop for different values of one specific parameter. What I would like to do however is have a matrix of parameter values and tell fsolve to pick a new row of that matrix each time as parameter values until it has run down all the rows.

I just need some general guidelines and the commands. Much appreciate the help...
