Help Center Help Center. Starting in Rb, mod no longer finds the modulus for each coefficient of a symbolic polynomial. For more information, see Compatibility Considerations. To find the remainder, use rem. If a is a polynomial expression, then mod a,b returns the unevaluated modulus of the polynomial. Find the modulus after division when both the dividend and divisor are integers. Find the modulus after division when the dividend is a rational number, and the divisor is an integer. Find the modulus after division when the dividend is a polynomial expression, and the divisor is an integer. If the dividend is a polynomial expression, then mod returns a symbolic expression without evaluating the modulus. To evaluate the modulus for each polynomial coefficient, first extract the coefficients of each term using coeffs. Next, find the modulus of each coefficient in c divided by Reconstruct a new polynomial using the evaluated coefficients. For vectors and matrices, mod finds the modulus after division element-wise.

Mod function matlab a and b must either be the same size or have sizes that are compatible for example, a is an M -by- N matrix and b is a scalar or 1 -by- N row vector.

For floating-point input arguments, the output data type is the same as the inputs. The mod function ignores and discards any fimath attached to the inputs. The output is always associated with the default fimath. Calculate the mod of two fi objects. Convert the fi inputs in the previous example to double type and calculate the mod.

Arithmetic functions include operators for simple operations like addition and multiplication, as well as functions for common calculations like summation, moving sums, modulo operations, and rounding. For more information, see Array vs. Matrix Operations. Matrix operations follow the rules of linear algebra, and array operations execute element by element operations and support multidimensional arrays. The period character. Two inputs have compatible sizes if, for every dimension, the dimension sizes of the inputs are either the same or one of them is 1. The default is double precision. If you use the smallest integer type that accommodates your data, you can save memory and program execution time.

Use piecewise to define the sawtooth wave that is increasing linearly for the first half of a period, and then decreasing linearly for the second half of a period. Cancel Copy to Clipboard. All variables must have data types that support the calculation. Usage notes and limitations: bit integers are not supported.

Version History Introduced before Ra expand all Ra: Perform calculations directly on tables and timetables The mod function can calculate on all variables within a table or timetable without indexing to access those variables. See Also powermod quorem rem coeffs. When possible, rem attempts to produce exact integer results by compensating for floating-point round-off effects. Examples collapse all Remainder After Division of Scalar. Inputs a and m must either be the same size or have sizes that are compatible for example, a is an M -by- N matrix and m is a scalar or 1 -by- N row vector.

Toggle Main Navigation. Calculate the mod of two fi objects. Documentation Examples Functions Videos Answers. If one argument is a scalar, the mod function expands the scalar input into an array of the same size as the other input. Use mod functions to define the sawtooth wave for each period. MathWorks Answers Support. Answered: John D'Errico on 9 Feb at Result of modulus operation, returned as a scalar, vector, matrix, or multidimensional array. Reload the page to see its updated state. If one input has an integer data type, then the other input must be of the same integer data type or be a scalar double.
