Step 2: Use function with proper syntax to sort the input data. The means in the three component models are different, suggesting that the model distinguishes among the three iris species. X correspond to variables. Name-value arguments must appear after other arguments, but the order of the I = [1 2 3; 4 5 6; 7 8 9]; Explanation: The content of the variable can be edited using command or can be edited from the variable editor. You can use try / catch statements to help manage error messages. The k-means++ algorithm assumes the number [X, Y] = gradient[a]: This function returns two-dimensional gradients which are numerical in nature with respect to vector a as the input.
