Successive differences will be the lengths of intervals that add up to 1. The data type (class) must be a built-in MATLAB numeric type. you can generate N random numbers in the interval (a,b) with the formula r = a + (b-a).*rand(N,1). We will not sell or rent your personal contact information. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. In fact, the problem here is that MATLAB is rounding x to 5 digits for display purposes. Round the elements of a vector to retain 2 significant digits. A.
