How to find the derivative without using a symbolic function in Matlab?

I want to write a function in Matlab to find out if a word is a Palindrome without using the fliplr(x) function.

I have a problem for my final project, it's about shape design of multi segments rotating disk using matlab optimization toolbox. say if I have given input parameters Lmin, Lmax, L2, Lm, P2,Pm,(R2,...,Rm),N (all this parameters are known) where L, P...

I wish to simulate the 'randn' function in Matlab using only the 'rand' function but cannot seem to get it to work. I wonder if it may hav something to do with the central limit theorem?

How would I be able to find the length of a vector only using simple arithmetic and loops? For example, I can't use functions like find(), length(), fft(), etc.

A water tank consists of a cylindrical part of radius r and height h, and a hemispherical top. The tank is to be constructed to hold 500 m^3 when filled. The surface area of the cylindrical part is 2*pi*r*h, and its volume is pi*r^2*h. The surface area...

Any processes such as in factories that implement the matlab objective function. Example die process.

the same signal is received by two sensors which are at different positions. how to find out the delay between the signals received by these sensors using Matlab.delay must be as accurate as possible.

Can anyone write a MATLAB program to find the derivative of the following: f(x)=xcos(x) f(x)=x^{cos(x)} The inputs to the program are: x h The outputs are f'(x) = D(3,3), The estimated error = D(3,3) - D(3,2) Theoretically, I can solve it using...

I need to sum the values of all elements of 1st row using the summation function (symsum). How can I accomplish this? The matrix is a 512X512 one. This is the syntax: symsum(k,1,512) k is a symbol only... Can I refer it as an element? I tried inputting...
