finite-difference code snippets in matlab

central finite differencing of a multivariate function in matlab

estimate f’(x) at xi =𝟏, using both forward and centered finite difference in matlab

for n = 2:nt for i = 2:nx % finite difference scheme (explicit time marching) t(i, n+1) = t(i, n) + alpha * dt / dx^2 * (t(i+1, n) - 2 * t(i, n) + t(i-1, n)); end in matlab

generate a code using appropriate finite difference schemes with a consistent order of o(h2 )v in matlab

suppose f(x) = cos(x), and we want to estimate f’(x) at xi=𝝅/2, (so f(xi )=0) using centered finite difference. what is the true value of f’(xi ) show the code for the true value of f’(xi ) as well? in matlab

suppose f(x) = exp(x), and we want to find f’(x) at xi =𝟏. estimate f’(x) at xi =𝟏, using both forward and centered finite difference in matlab
