Note: IF the value of column 4 in matrix A is the same, so all data will be grouped in one group My questionis: How to call each group from matrix A? Since, I wanna work with the data in each group? I hope the

A matrix of this shape is often referred to as a row vector. Get A = [12 62 93 -8] A = 1×4 12 62 93 -8 Get sz = size(A) sz = 1×2 1 4 Now create a matrix with the same numbers, but arrange them in two rows. This matrix has two rows and two columns. Get ...
In the process of learning the VIKOR algorithm, we need to use the "end+1" and matrix branch operations when determining the group utility value and the individual regret value. If "end+1" is deleted in this step, what will happen to the result? Change? Delete the code after "end+1"...
For matrix columns that contain any NaN value, mean computes with the non-NaN elements. For matrix columns that contain all NaN values, the mean is NaN. Get M = mean(A,"omitnan") M = 1×4 1.7700 0.1675 NaN -1.3800 Weighted Mean Since R2024a Copy Code Copy Command Create a ...
Create a complex scalar with zero imaginary part. Get z = complex(12) z = 12.0000 + 0.0000i Verify that z is complex. Get isreal(z) ans = logical 0 Input Arguments collapse all a— Real component scalar | vector | matrix | multidimensional array Real component, specified as a ...
Then, you create a 2x2 slice of the original array storing from the second value to the end in both dimensions, arr_2. Notice that the Python indexing is 0-based, so the second element has the index 1. Finally, you are printing arr_2 to verify that it is a 2x2 array. Now you ...
