WebEven though A is a 7-by-3 matrix and mean(A) is a 1-by-3 vector, MATLAB implicitly expands the vector as if it had the same size as the matrix, and the operation executes as a normal element-wise minus operation.. The size requirement for the operands is that for each dimension, the arrays must either have the same size or one of them is 1. WebMay 22, 2013 · The subscript vector must be either of the same dimensions as the original matrix or a vector with the same number of elements. For instance, if we have: A = [10 …
How to find sum of elements of an array in MATLAB?
WebDec 2, 2024 · Solution 1: Just use a loop. So it did exactly as we need it to do, operating on each element of M separately. Note that the loop uses a linear index, treating the matrix as if it were a vector of elements. This works in MATLAB, so I did not need to create a double loop on the rows AND the columns of M. WebMay 21, 2024 · energie {n} is a 5 element matrix. You are wanting the 3rd element of it, so energie {n} (3) will give you the element. If you had done energie {n} = {Ea Ed} then energie {n} is a cell array containing 2 elements, where the first element is a scalar and the second element is a 4 element vector. In this case energie {n} {2} (2) would work. Share scout beavers badges

WebMay 23, 2013 · The subscript vector must be either of the same dimensions as the original matrix or a vector with the same number of elements. For instance, if we have: A = [10 20 30; 40 50 60; 70 80 90]; and we want to extract A ( [1 3], [1 2]) using logical indexing, we can do either this: Ir = logical ( [1 1 0]); Ic = logical ( [1 0 1]); B = A (Ir, Ic) WebNov 5, 2024 · calling elements in matrix .

Else, if you give a vector as the index (like in your question), MATLAB returns … WebIf you want to determine the actual column major indices to access the matrix, you can generate a vector from 1 to N where N is the total number of elements in your matrix, then reshape this matrix into the desired size that you want. After, use the same logic above to get the actual linear indices: scout becoming a lady
