![]() Due to the inexact representation of floating-point numbers on a computer, real (or complex) inputs may lead to unexpected results. You can also debug M-files in the command window. The > symbol indicates that the program can process the values you assigned to the variables. It’s prompt is indicated by two right-facing double angle quotation marks. Limitations Arguments X and Y should be integers. The MATLAB command window is the section wherein you will enter data, run functions, and other MATLAB files. ![]() X and y are congruent (mod m) if and only if mod(x,m) = mod(y,m). The mod function is useful for congruence relationships: Remarks So long as operands X and Y are of the same sign, the function mod(X,Y) returns the same result as does rem(X,Y). mod(X,Y) always differs from X by a multiple of Y. Returns the remainder X - Y.*floor(X./Y) for nonzero Y, and returns X otherwise. To run Dynare, you have the choice between running it on MathWorks MATLAB (proprietary) or GNU Octave (free software). Modulus (signed remainder after division) For those who want to quickly have something running, this page explains how to setup Dynare on Windows or macOS and to run your first model (.mod) file. Replacing the arithmetic expression with ~mod(dataInput, 1) will make it only 50% faster than the code that checks for imaginary parts.Mod (MATLAB Function Reference) MATLAB Function Reference 5, therefore in MATLABmod(1,2) 1 (remember, mod. So long as operands X and Y are of the same sign, the function mod(X,Y) returns the same result as does rem(X,Y). The mod function is useful for congruence relationships: x and y are congruent (mod m) if and only if mod(x,m) mod(y,m). What makes you so sure that the design team didn't first assign operators (including modulo) and then choose a comment character from what was left. In MATLAB the function mod(x,y) does this operation, and rounds up to the nearest integer. The inputs X and Y must be real arrays of the same size, or real scalars. mod(X,Y) and rem(X,Y) are equal if X and Y have the same sign, but differ by Y if X and Y have different signs. M mode (A,vecdim) computes the mode based on the dimensions specified in the vector vecdim. The MATLAB function equivalent to np.remainder is mod. the answer to why) is not used for modulo is because it is used for comments. It is equivalent to the Python modulus operatorx1 x2 and has the same sign as the divisor x2. The looped call is quite a bit slower mostly due to the function overhead. am304 You cannot logically conclude that the reason (i.e. ![]() > tic for ii = 1:100000 fnIsInteger(x(ii)) end toc If you want to evaluate 11 (mod 7) 11 ( mod 7), you need the largest multiple of 7 7 that's less than or equal to 11 11. This same exact process applies for negative numbers. > tic for ii = 1:100000 ~mod(x(ii), 1) end toc Therefore 31 7 4 + some number 31 7 4 + some number, where your goal is to determine what some number some number is. If you need to care about the imaginary part then you need to deal with it separately.įor my applications, inputs with imaginary components shouldn't be considered a valid integer, so I have this: function boolResult = fnIsInteger(input)īoolResult = (imag(input) = 0) & (round(input) = input) ![]() I just wanted to point out that the provided methods all test for whether the input is a Gaussian integer, meaning that the real and imaginary parts are both integers. ![]()
