In this example, we will use the diff function with a matrix input. Please note that the number of elements in the output is 8 this is because, in the 2nd order difference, 2 iterations of difference calculation are performed. Please note that the formula for the 2nd order difference is diff (diff (A)).Īs we can see, we have obtained the 2nd order difference between adjacent elements as the output of the diff function. For this, we will pass ‘2’ as the second argument, which signifies that the 2nd order difference is to be calculated. In this example, we will use the diff function to calculate the 2nd order difference for a vector input. In this example, we will use the diff function for a vector input.Īs we can see, we have obtained the difference between adjacent elements as the output of the diff function. Given below are the examples of Matlab diff: Example #1 Please note that if we have ‘n’ number of elements in a vector or array, the diff function will return ‘n-1’ elements in the output. The formula that diff function uses is: D =, where ‘n’ is the number of terms in the array.The dimension (row or column) along which the diff function will work is decided by the argument ‘dim’. D = diff (A, o, dim) is used to return the difference between the adjacent rows or columns of the input matrix A.D = diff (A, o) is used to return the ordered difference between the adjacent elements in input A.D = diff (A) is used to return the difference between the adjacent elements in input A.Given below is the syntax of the diff function: Hadoop, Data Science, Statistics & others
