I want to normalize the elements of the following vector using the first element. I want the first element of my vector 'stock_market' to be 100 and the other elements of the vector to be normalized according to that value. I used the normalize function:
stock_market = readmatrix('^FTSE.csv' , 'Range' , 'F2:F313')
norm_stock_market = normalize(stock_market , 'scale' , 'first' , '100')
but I am getting an error.
Any help would be appreciated. Thanks!

A = [10 20 15 12];
A_new = A/A(1)*100;
Using normalize()
normalize(A, 'scale', 'first')*100
