On this happy twenty-four hours I volition write an article that I mean value volition last really useful, ie an article nigh the fastest formula of the inverse 2x2 matrix. However, truly non the formula that I volition brand fast, but the agency that I volition speed up, too then you lot tin efficiently run the fourth dimension inwards the bear witness later.
Inverse formula of matrix:
Information:
A-1 = The inverse of a matrix A
Det (A) = Determinan a matrix A
Adj (A) = Adjoin a matrix A
To know how fast nosotros only practise inwards the matter.
Problems example:
Find the inverse of the next matrix !
Answer:
For a quick agency the telephone commutation lies inwards the search for the adjoint matrix, if the adjoint has been flora it is really slow to piece of job on the inverse matrix. Here's a quick agency to detect the matrix adjoint:
- Move or swap the positions of elements that be on the commencement row of the commencement column amongst the instant row of the instant column,
- The commencement too instant row elements too the commencement ii row column elements are multiplied past times -1.
Then the adjoint of the matrix H5N1 is:
Then await for determinants using the green way.
Det H5N1 = (1 ten 4) - (2 ten 3)
Det H5N1 = 4 – 6
Det H5N1 = -2
Then the inverse of the inwards a higher house matrix is :
How slow too fast friends are non to solve the 2x2 inverse matrix ?
H5N1 few articles this time. Sorry if in that place is a incorrect word.
Finally I said wassalamualaikum wr. wb.
