Hi there, I have a problem with regard to the codes that I have created using Mathematica. Being a novice user to Mathemaica, I have tried to generate the best possible code that I could. I have run the code and got the outputs. However, the result that Iam getting, eventhough is pretty close to the available one, but not the quite result that I need. The big probelm Iam facing at the moment is that I could not identify the source of errors or to which stage that the errors started. My question is that Iam looking for an experienced and expert user of Mathematica for a private hire. His task would be to improve my codes that I have created. Brief content of the problem that Iam tackling is related to solving matrices, solving linear equations, Do-loop iteration. please email me at email@example.com for further info. Thank you.
