im looking at creating an
adjacency
matrix built with rows r1, and columns c1, with a float value. i have managed to read the the values from a text file, set out like: r1,c1,float1 r2,c2,float2 etc... i am having trouble converting these values into an
adjacency
matrix. thanks

You don't necessarily need a matrix class. All you need is arrays. Better yet, you should use std::vector < std::vector<float> >, as a 2d array.
Adjacency
matrix are fairly easy to implement with the cost of O(row^2) of space. What exactly are you having trouble with, in respect to
Adjacency
matrix.

Well to make an
adjacency
matrix, you'll definitely need a matrix! You could use a 2D array: [url]http://www.fredosaurus.com/notes-cpp/arrayptr/22twodim.html[/url]. The problem with this is that you'll have to know the size of the matrix before you start, which is not always the case. Dave
