This assumption suffices for most engineering and scientific problems. If you differentiate a multivariate expression or function f without specifying the differentiation variable, then a nested call to diff and diff(f,n) can return different results. This is because in a nested call, each differentiation step determines and uses its own differentiation variable.

Try in MATLAB Mobile. y0 = 0.1;. yy = fsolve(dfxy,y0). is this possible without using symbolic toolbox? I get error like 'Function 'diff' is not supported ...
Solve Differential Equation with Condition. In the previous solution, the constant C1 appears because no condition was specified. Solve the equation with the initial condition y(0) == 2.The dsolve function finds a value of C1 that satisfies the condition.

03.05.2015 · If you have a numerical vector and you'd like to differentiate it, then the gradient function is your friend.. If you want to differentiate a symbolic expressing then the Symbolic Math Toolbox is the only way to go within Matlab. If pen&paper together with wolframalpha.com does not serve you, there is no way around to buy the toolbox or use alternatives like Wolframs …
Now we will start showing you how, using MATLAB Symbolic Toolbox, ... then we will be able to create and manipulate formulae without giving x a value first.
Numerical Differentiation MATLAB Functions for Numerical Differentiation: diff() polyder() MATLAB is a numerical language and do not perform symbolic mathematics ... well, that is not entirely true because there is “Symbolic Toolbox” available for MATLAB.
