how to solve a one dimension thermal diffusion equation

hi

i am new to these forums and new to labview.

please see if you can help me with this -

i am taking 8 sets of data - over 2 minutes (120 data points - sampled at one second apart. The 8 data points are along 8 equidistant points on a rod and the data itself is the temparature, recorded as a voltage (v) by 8 thermistors

The data satisfies the following equation -

d^2v/dx^2 = k d^2v/dt^2

that is the one dimensional laplacian of the voltage = k times the 2nd time derivative of the voltage

how to solve the equation in labview !!??
