1   Pass
nterms = 10; term0 = randi(10) ratio = (-1)^randi(2)*randi(10) correctsequence = term0*ratio.^(0:nterms-1); for position = 1:nterms errorsequence = correctsequence; errorsequence(position) = errorsequence(position) + (-1)^randi(2)*randi(50); [errorposition, truesequence] = find_error(errorsequence); assert(errorposition == position && isequal(truesequence, correctsequence), 'failed test 1 at position %d', position); end

2   Pass
nterms = 15; term0 = randi(10) ratio = (-1)^randi(2)*randi(10) correctsequence = term0*ratio.^(0:nterms-1); for position = 1:nterms errorsequence = correctsequence; errorsequence(position) = errorsequence(position) + (-1)^randi(2)*randi(50); [errorposition, truesequence] = find_error(errorsequence); assert(errorposition == position && isequal(truesequence, correctsequence), 'failed test 2 at position %d', position); end

term0 = 6 ratio = -7
