BLOCK_LEVINSON(Y, L) solves the matrix equation T * x = y, where T is a symmetric matrix with block Toeplitz structure, and returns the solution vector x. The matrix T is never stored in full (because it is large and mostly redundant), so the input parameter L is actually the leftmost "block...

This program checks whether a point (x,y) lies inside,outside or on a circle defined by 3 other points.Syntax: iscircle(X,Y,x,y), where X=[x1 x2 x3] and Y=[y1 y2 y3]. Thus, a circle can be made out of these 3 points-->(x1,y1), x2,y2)&(x3,y3).Program checks whether point (x,y) lies inside,outside...
