This example shows how perform right-array division on a 3-by-3 magic square of fi objects. Each element of the 3-by-3 magic square is divided by the corresponding element in the 3-by-3 input array b. The rdivide function outputs a 3-by-3 array of signed fi objects, each of which has a word length of 16 bits and fraction length of 11 bits.The documentation clearly states "It is seldom necessary to form the explicit inverse of a matrix. A frequent misuse of inv arises when solving the system of linear equations Ax = b.One way to solve the equation is with x = inv(A)*b.A better way, from the standpoint of both execution time and numerical accuracy, is to use the matrix backslash …To compute the logarithm of a product, we can compute the sum of the logarithms: log (product (x i )) = sum (log (x i )) Thus, we can compute the values of (n+1-i)/i for all i, take the logarithm, and then sum up the first k values to get the result for a given k. This code accomplishes that using cumsum, the cumulative sum.MATLAB - Division (Left, Right) of Matrics. You can divide two matrices using left (\) or right (/) division operators.

If the size of our dataset is between 100 to 10,00,000, then we split it in the ratio 60:20:20. That is 60% data will go to the Training Set, 20% to the Dev Set and remaining to the Test Set.the answer given by u works well..but my aim is to divide two polynomial expressions[1+x+x^2]/[1+x] directly.the output must be polynomial expression
Description.

You can divide two matrices using left (\) or right (/) division operators. Both the operand matrices must have the same number of rows and columns. Practice. The find () function in MATLAB is used to find the indices and values of non-zero elements or the elements which satisfy a given condition. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition. It returns a vector that contains the linear indices.Addition, subtraction, multiplication, division, power, rounding.

You can introduce 3-dimensonal matrix. If your matrix size is NxM and each element of this matrix contains k elements, you define matrix B of the size NxMxK. By calling B (2,3,:) you will access all the elements of the entry (2,3). Alternatively, you can define a cell matrix, so that every entry is cell array.
