Help Center Help Center. Because symbolic variables are assumed to be complex by default, abs returns the complex modulus magnitude by default. If z is an array, abs acts element-wise on each element of z. Assume x is real, and repeat the calculation. Remove assumptions on x for further calculations.

Help Center Help Center. Intermediate quantities are calculated using the fimath associated with a. The output fi object, y , has the same local fimath as a. Intermediate quantities are calculated using the fimath associated with a and the output fi object y has the same local fimath as a. See Data Type Propagation Rules. Intermediate quantities are calculated using the fimath object F. The output fi object, y , has no local fimath. This example shows the difference between the absolute value results for the most negative value representable by a signed data type when the 'OverflowAction' property is set to 'Saturate' or 'Wrap'. Calculate the absolute value when the 'OverflowAction' is set to the default value 'Saturate'. Calculate the absolute value when the 'OverflowAction' is set to 'Wrap'. This example shows the difference between the absolute value results for complex and real fi inputs that have the most negative value representable by a signed data type when the 'OverflowAction' property is set to 'Wrap'. This example shows how to specify numerictype and fimath objects as optional arguments to control the result of the abs function for real inputs. When you specify a fimath object as an argument, that fimath object is used to compute intermediate quantities, and the resulting fi object has no local fimath.

Distributed pipelining and constrained output pipelining can move these registers. Values: 'off' 'on'. Other MathWorks country sites are not optimized for visits from your location. Based on your location, we recommend that you select:. Toggle Main Navigation. For further computations, clear the assumption on x by recreating it using syms :. Algorithms collapse all Absolute Value The absolute value of a real number is the corresponding nonnegative value that disregards the sign. Off-Canvas Navigation Menu Toggle. If X is complex, then it must be a single or double array. Compute the squares of re and im using one of the following objects:. Toggle Main Navigation.

Specify the time interval between samples. Block Parameter: SampleTime. The fimath object F if F is specified as an argument. But it can make a difference when you are calling library routines that are expecting a complex array, especially if you are expecting them to update the array "in-place". I have a matrix of x filled with real and complex number; ex. This will work for a m by n matrix too. Examples collapse all Absolute Value of Scalar. Answers Support MathWorks.
