Please look into the attachment for the 'Grid Method' offlatness error measurement of a surface pertaining to the course'Metrology'. And provide me with the MATLAB or Python program tofind the flatness error. In this case, the answer should come as'8.5' when you input the measured values table ( the first table inthe example ). While adjusting rows, take a look at the red numberswritten on top of the table. Just invert the sign of the first rowlast element and write above that element ( here we write +3 ).Then divide this number by [number of columns -1] , here it is +3divided by 3 is equal to +1. Now decrease in steps of +1 and writeover the corresponding elements of the first row from right to left( here we get 0 +1 +2 +3). Now add these numbers to all elements ofcorresponding columns. Thus row adjustment is done. Proceed insimilar way for column adjustment first by making first column lastelement as zero.
