Note: R2021b gives numeric result but I use R2021a matlab software. 2. The second question is my codes ends with numeric values of X,Y and Z . I want to see final results as a equation below, How I code this re
I am trying to convert a symbolic matrix to a numeric array, but am having no luck. Please refer to the code below. 테마복사 Z = sym(zeros(200,1)); for i = 1:200 syms omega_n; lambda = i*1e-7; k_zeta = 2*pi/lambda; kappa_n = n*pi/W; k_n = sqrt(((kappa...
