I need to create matrix without using loops
显示 更早的评论
Topic : Numerical Differentiation Using Matlab
Below is given table for the time t and its corresponding x position
Use forward and central differential scheme to compute velocity and acceleration by constructing differential matrix for the first derivative and multiplying the matrix and vectors (not allowed to use loop) as it is matrix based calculation.
Forward differential scheme is = x(i+1)-x(i) / t(i+1)-t(i)
***Expecting to use Sparse*** However open to use for other function as well
Please note end position is same as start position hence velocity should be equal for t1 and t10 (Please provide just Matlab Code for this)
Time t = 0 0.0775 0.2346 0.3015 0.3682 0.4345 0.5006 0.5665 0.6321 0.6974
X position 3.1909 3.1818 3.1547 3.1104 -0.0499 -0.0499 3.1104 3.1547 3.1818 3.1909

Read about the function diff, gradient.
