These key function in Matlab is used to create a symbolic representation of data is: sym() or syms if user have multiple symbols to make. Defining Symbolic Expressions User can define symbolic functions using the sym function command and syms function command. Here is an example for creating ...
(3) In non-symbolic representation task, the effect of numerical ratio on fixation counts was larger for HMA group than that for LMA group under inhibition condition, indicating MA might arise from a basic level deficit in numerosity processing....
The results demonstrate that text was the one representation that was attended most and can therefore be regarded as the reference representation in all useful combinations. Even though fewer gaze switches were observed between text and formulas than between text and graphics, performance (time on ...

The nested (Horner) representation of a polynomial is the most efficient for numerical evaluations: syms x h = x^5 + x^4 + x^3 + x^2 + x; horner(h) ans = x*(x*(x*(x*(x + 1) + 1) + 1) + 1) For a list of Symbolic Math Toolbox simplification functions, seeChoose Fun...
However, the subs function seems to be incompatible with symbolic variable z. On the other hand, the expression int( A4*exp(y*z), y, -r,0) cannot be handled via tf('s'), so I need to first apply a symbolic representation here. ...

(Or "symbolic math") The use of computers to manipulate mathematical equations and expressions in symbolic form, as opposed to manipulating the numerical quantities represented by those symbols. Such a system might be used for symbolic integration or differentiation, substitution of one expression into...
Open in MATLAB Online I like to start with the PDF and symbolically reach the quantile of the normal distribution. I discover two unexpected behaviors: 1. My symbolic representation is simplified in an unexpected manner 2. The finverse function fails in the CDF. ...
