Would tell FORM to create an expression named myexpr, replace therein the symbol y by x, and print the result on the screen.

External communication with other software programs.

Output into various formats (plain text, Fortran code, Mathematica code).

Fast trace calculation especially of gamma matrices.

Powerful pattern matching and replacing.

Multi-threaded execution, parallelized version for computer clusters.

Arbitrary long mathematical expressions (limited only by disk space).

Definition of mathematical expressions containing various objects (symbols, functions, indices.

Its original author is Jos Vermaseren of Nikhef, the Dutch institute for subatomic physics.It is widely used in the theoretical particle physics community, but it is not restricted to applications in this specific field.

It reads text files containing definitions of mathematical expressions as well as statements that tell it how to manipulate these expressions. FORM Developer(s)įORM is a symbolic manipulation system. With the Symbolic Math Toolbox comes a new matlab datatype - symbolic object. The most common problem that people have is with how Matlab and Maple interact. Matlab/Maple interaction Maple's usually straightforward to use. Matlab - the Symbolic Toolbox based on Maple. Unfortunately, the error message does not appear that much on the web. While trying to solve a DAE system with Symbolic Math Toolbox, I keep getting the same error. Very useful for rearranging, factorizing, simplifying, integrating, solving. Introduces the Symbolic Toolbox for using MATLAB to perform symbolic calculations (basically algebra on a computer). User Friendly Matlab-Toolbox for Symbolic Robot Dynamic. Blue Sky Functional Test Toolbox - Board Test Workshop Home Page. Structural functionalism Conflict theory Symbolic Interactionism.

Accessing Symbolic Math Toolbox Functionality. Build mathematical models from first principles using Symbolic Math Toolbox, including systems of differential equations.

Symbolic Math Toolbox can generate code for MATLAB functions, MATLAB function blocks for use in Simulink models, and custom equation based components for use in Simscape.

However, I'm not sure what you have against vpa as it is actually a much cleaner way to do this: b1 = vpa(a)*x or b1 = vpa(a*x). If you want a more automatic way of converting floating point values to "exact" decimal representations with sym, you might try something like this: syms xĠ.000000000000000000000000010000000000000000384948697491918*x

Matlab has probably chosen the other method as the default because the representation is not easily confused with floating-point. sym(0.1,'d') uses the floating-point value of 0.1 to length digits. However, care should be taken in how you do this, as the following example illustrates: syms xĪs you know, many floating-point decimal values are not exact. If you want to use decimal approximation/representation, then you'll need to directly specify that. As per the documentation for sym, the default conversion method for numeric values is rational approximation/representation, the 'r' flag.
