Of course the options begs the questions as to where in the workflow does this matrix need to be created? Is it a need that this step be calculated within the process or can the process not be broken down into a series of steps... some requiring arcmap be open and running and...
So these cell values of the confusion matrix are addressed the above questions we have. By seeing the matrix representation, we can understand where the model is much more accurate and we can clearly know where the model not able to predict properly. This helps in tuning the right model para...
Rows also have a different interpretation as row space. So whenever we are asked to find the number of dimensions in the row space of a matrix, we can just put the inbuilt functionlen(M)in our code to answer such questions. The following code shows how to call a whole row of a matri...
