In Python, the following equality holds: a // b = math.floor(a / b) The physical interpretation of the floor division is that given a group and items, how many parts each member of the group gets when the items are shared between the group.Description. rem (a,b) finds the remainder after division. If b <> 0 , then rem (a,b) = a - fix (a/b)*b. If b = 0 or b = Inf or b = -Inf , then rem returns NaN. The rem function does not support complex numbers: all values must be real numbers. To find the remainder after division of polynomials, use quorem.In our example, we'll split the first and last names listed in column A into two different columns, column B (last name) and column C (first name.) Click the "Data" tab at the top of the Excel Ribbon. Click the "Text to Columns" button in the Data Tools section. In the Convert Text to Columns Wizard, select "Delimited" and then click "Next."Note the curly braces. If you used regular MATLAB indexing, like so: det1 = det(A(1)) %% DOESN'T WORK you would get an error, because det() doesn't work on cell arrays. The dereferencing curly braces are needed to remove the outer layer (the cell array) and get at the inner layer (the matrix). To divide by a number, you just do normal division: My code so far is: function [q,r]=Divide (x,y) q=x/y. q=floor (q) %so values are rounded down to allow remainder. r=x- (q*y) %my remainder value. end. q is the whole integer, and r is the remainder. Also i want to be able to insert values for 'x' as a vector but act as an integer value. All help would be great!Check that the two matrices can be multiplied together. To multiply two matrices together, the number of columns in the first matrix must equal the number of rows in the second matrix. If this does not work in either arrangement ([A] * [B]-1 or [B]-1 * [A]), there is no solution to the problem. For example, if [A] is a 4 x 3 matrix (4 rows, 3 …Cell mode can be enabled or disabled from the Cell menu.
