hello people.i am new to matlab and thriving on tutorials and books to get a grip on this awesome computational tool.with an aim of calculating the reaction forces of the rigid supports that hold together a rigid rope subtending an angle from the horizontal,i derived the static equations(5 unknowns hence 5 equations) and framed a matrix to solve the set of linear equations by left division.i am getting an error which reads " single precision error" and the result is a column of NAN.where am i am going wrong and what remedial measures to take?

i have uploaded the code here

Pare the code down to the minimum to show the formulation and the error--start w/ just the offending line and the error pasted from the command window; it's quite possible that will be enough for experienced folk to see the problem.

I don't recall seeing that particular error before--have you used single precision in the formulation? If so, why not use the default double precision and see what happens? Certainly doesn't sound like a memory-intensive problem where there's any need to try to economize on storage.
