The absolute value (or modulus) of a real number is the corresponding nonnegative value that disregards the sign. For a real value, a, the absolute value is: a, if a is greater than or equal to zero -a, if a is less than zero abs(-0) returns 0. ...
The absolute value of a complex numberz=x+y*iis the value∣z∣=√x2+y2. Here,xandyare real numbers. The absolute value of a complex number is also called a complex modulus. Tips Callingabsfor a number that is not a symbolic object invokes the MATLAB®absfunction. ...
For a real value,a, the absolute value is: a, ifais greater than or equal to zero -a, ifais less than zero abs(-0)returns0. The complex magnitude (or modulus) is the length of a vector from the origin to a complex value plotted in the complex plane. ...

linear inequality constrains based on absolute valuesIt would make more sense if the conditions were "and" and you processed the intersection of the constraints in two pieces, one for negative x and the other for non-negative x, and took the best between the two of those.part...
(Chebfun exampleapprox/AbsoluteValue.m) Peter Lax mentioned to me recently an example that no doubt various people have thought about over the years. Suppose we think of x^2 as a given number and we try to find its square root by solving the equation ...

There are numerous ways to specify the value of Ts. We have set Ts from within the model's PreLoadFcn callback (see Create Model Callbacks (Simulink)). You can set the value of Ts in the base workspace at the MATLAB® Command prompt as well....
error considered for each state on each time step is determined by either the relative tolerance or the absolute tolerance, whichever results in a larger tolerance. The solver calculates the acceptable error based on the relative tolerance by multiplying the relative tolerance and the state value. ...
