That is, it transforms a given MATLAB code for the evaluation of some mathematical function into a new MATLAB code for the evaluation of user-specified derivatives of that function. ADiMat is based on a source transformation approach.

The variable of differentiation with the desired order ofД«y default different symbols are considered to be independent.Д«ut a functional dependence can be asserted using square brackets.ADiMat is a software tool implementing the technology of automatic differentiation (AD) to programs written in MATLAB which is a trademark of The Mathworks, Inc. To which differentiation is to be performed, or a list pairing The second input is the variable with respect It's first input is the expression toД«e differentiated. Y y = y(x) % Apply function to numerical values stored in x. > y = matlabFunction(y) % Convert symbolic expression to a MATLAB function Symbolic expressions may be converted to function handles with > yy = subs(y,x,xx) % Substitute the numerical values in xx for variable x in symbolic expression y, compute and store results in yy. The subs() command may be employed to perform numericalД¬omputations according to symbolic formulas. Symbolic expressions can be graphed directly with ezplot(). Without providing an explicit formula for the functional dependence. You can require MATLAB to treat certain symbols as functions of others > diff( x*a^2, a ) % This forces MATLAB to treat 'a' as the variable of differentiation.

> diff( x*a^2 ) % MATLAB treats 'a' as a fixed parameter and 'x' as a variable. With respect to which you want differentiation to be performed. Sometimes you need to specify explicitly the variable > diff( 1/(x^2+1), 11 ) % A computation which would be straightforward, but quite tedious by hand. Syntax with the matlabFunction() command.ДЄns course the Symbolic toolbox method diff()Д¬an be applied repeatedly to compute higher order derivatives,Д«ut it also admits an optional input specifying the order of differentiation. You can, however, convert a symbolic expression to MATLAB's 'ordinary' Notice that symbolic expressions in MATLAB do not employ The following MATLAB session illustrates diff(). Symbolic toolbox diff() method will be used.) If you pass diff() a symbolic expression, then the The system determines which method to invoke based on the argument(s) in the call. In MATLAB, diff() is a so-called 'overloaded' method. With the arithmetic operator diff() introduced earlierДЇor computing differences between consecutive elements in numerical arrays. (The Symbolic toolbox method diff() is not to be confused This method may be used to differentiate sums, differences, products, quotients, rootsДЄnd compositions of a host of functions including all the familiar trig functions, The Symbolic toolbox method diff(), however, isДЄ much more powerful and versatile tool for performing symbolic differentiation. Shows that $$ -ДЄ result that can easily can be verified by hand. May be differentiated with the polyder() method. In MATLAB (or Octave) polynomials (encoded as row vectors of coefficients) Each of our target CASs is capable of symbolic differentiation.
