Tridiagonal matrix - Gaussian elimination, loop
I have to seek help after running out of resources on this. I have a 39X39 tridiagonal matrix. We are not allowed to use Matrix operations in matlab. we r using iterative methods to solve this. We need to do gaussian elimintation on the system to solve it. It is also called a PADE scheme. We defined 3 vectors (a,b... 18 Mar 2010 22:20

how to vectorize this in matlab
hi all i want to eliminate the for statement...but the boundaries need to be fixed. is there a better way of writing this? i am using matlab. thanks d(1) = fi(2) - a*fi(1); d(79) = fi(80) - c*fi(81); for i = 3:79 d(i) = fi(i-1) end where a and c are scalars. ... 18 Mar 2010 21:13

MINLP in MATLAB
Dear All, I am new to MATLAB and wondering if I can use any function (solver) to solve Mixed Integer Non-Linear Programming. I tried to find a solver by reading the help file in optimization toolbox, without much success (A year back in a course I used fmincon to solve a class room problem, but now I have a large sc... 18 Mar 2010 20:06
