MATLAB: Matrix question about array and absolute value

matrixmatrix arraymatrix manipulation

Write a user defined function, listDesDif, which will take an input of M and use the function from part a) to produce a matrix, it will then produce an array containing the numbers from this matrix. The array should be sorted in descending order of the absolute value of the difference between each individual element in the matrix and the first element in the matrix.

Why not just use the sort() function?

m=magic(5);
% Sort columns in descending order.
sorted_m = sort(m, 'descend')

first you should try yourself to solve the equation when there is just 1 line (1 a and a_1). see what's happening... and then increase to a couple of lines.

and it seem there is no (serial) correlation between a and a_1, so why not just use their expected values??? (im not a statics expert, but if they are not correlated it think that is a fair thing to do)

i will try to help with limited time, but then i first need to understand better what you want to do in words: what is the equation? do you have documentation on it? because i still find the equation obscure. i especially want to know what 'a' and a_1 and omega are (in words)
