WebNonzero elements of X, returned as a vector. More About collapse all Linear Indices A linear index allows use of a single subscript to index into an array, such as A (k). MATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Webli = [2, 0, 5, 7, 0, 9] li_new = [i for i, element in enumerate (li) if element!=0] print (li_new) Output: [0, 2, 3, 5] As you can see, the program returns indices for the non-zero elements. Using NumPy.array We can also access non-zero elements of a list using numpy. First, we import this module.
WebDescription of Mean Function in Matlab 1. M = mean (X) This function will return the mean of all the elements of ‘X’, along the dimension of the array which is non-singleton i.e. the size is not equal to 1 (It will consider the first dimension which is non-singleton). mean (X) will return the mean of the elements, if X is a vector.
