Question


In the LU decomposition method, I used a 4*5 matrix. However, L and U should originally come out as 4*5 matrices, but both come out only 4*4 matrices. What is the cause?

If I follow this code I get the graph, but when I hit enter in the command window it says "Array index must be a positive integer or logical value" on line 45. I don't know what this means... .
Hf_fig = figure; phi = 0: 15: 90; heel = pi*phi/180; B = 6.480; T = [ 1.729 1.575 1.163 0.600 -0.012 -0.693 -1.354 ]; w ...

If you follow this code, you will see a graph, but when you hit enter, line 45 keeps saying "'l' is an unrecognizable function or variable." But even though for I= 2:k is given, what is the problem?? ?
Hf_fig = figure; phi = 0: 15: 90; heel = pi*phi/180; B = 6.480; T = [ 1.729 1.575 1.163 0.600 -0.012 -0.693 -1.354 ]; w ...
