I try to declare a symbolic variable in MATLAB with this code: syms a; I do my computation on this variable and all thing is fine. But my problem is that, I don't know how can I give a number to variable and get the result as a number. For example the answer of my code is . answer=exp(-10*a); For instance I want to give 40 to "a" and get the ...

Each element in the matrix is a function of a lot of symbols, which I need somehow to convert into numbers. I have something like this:.

Create a symbolic number by using sym and compare it to the same floating-point number. sym (1/3) 1/3 ans = 1/3 ans = 0.3333 The symbolic number is represented in exact rational form, while the floating-point number is a decimal approximation. The symbolic result is not indented, while the standard MATLAB ® result is indented.

Symbolic Math in Matlab Matlab allows you to create symbolic math expressions. This is useful when you don't want to immediately compute an answer, or when you have a math "formula" to work on but don't know how to "process" it. Matlab allows symbolic operations several areas including: Calculus Linear Algebra Algebraic and Differential Equations

Nov 13, 2017 · use fplot () . This does a lot of work in the background to try to detect non-smooth areas and try to detect discontinuities, so it can end up taking a lot of computation. subs () in numeric values for the variables and double () the result to get numeric values. use matlabFunction to create a numeric anonymous function, and apply that function ...
