how do you do symbolic differentiation on function handle?

 Say if i define the following: 

 

 g = @(x) x/sqrt(x^2+1)

How do i get the derivative function for g, which i can then use to evaluate at different points?

I tried the symbolic math toolkit, and tried the following: 

 

>> syms x

>> f = x/sqrt(x^2+1)

f =

x/(x^2 + 1)^(1/2)

>> diff(f)

ans =

1/(x^2 + 1)^(1/2) - x^2/(x^2 + 1)^(3/2)

However, i cannot figure out how to turn this into a function handle/evaluate at different points. However, i prefer doing differentiation on function_handle.

Thank you very much!

You can use matlabFunction to convert a symbolic equation to a function. For example: 
 
syms x1 x2;
f1 = x1^2+x2^2;

Constructing piecewise symbolic function in Matlab

  I am trying to generate a piecewise symbolic function in Matlab. The reason it has to be symbolic is I want to be able to integrate/differentiate the function afterwards and/or insert actual values. I have the following function:    x^3/6 -> 0 < x <= 1 (1/6)*(-3*x^3+12*x^2-12x+4) -> 1 < x <= 2 (1/6)*(3*x^3-24*x^2+60x-44) -> 2 < x <= 3 (1/6)*(4-x)^3 -> 3 < x <= 4 0 -> otherwise I am trying to generate a piecewise symbolic function in Matlab.

Why Red, Green, Blue channels of image separetely are grayscaled (Matlab)?

  Answer When an image is loaded into MATLAB, it is usually stored as a matrix of values representing the intensities of the pixels in the image. For a color image, this matrix is usually three-dimensional, with one dimension for each color channel (red, green, and blue). To convert a color image to grayscale, one common approach is to take a weighted average of the red, green, and blue channels, using coefficients that reflect the relative importance of each color channel in human perception. In MATLAB, the  rgb2gray  function uses the formula  0.2989 * R + 0.5870 * G + 0.1140 * B  to convert a color image to grayscale, where R, G, and B are the red, green, and blue channels of the image, respectively. These coefficients NOTE:- Matlabhelpers.com  provide latest  MatLab Homework Help , MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil wit...
