在 MATLAB Online 中打开

syms t y(x)

f = y(x)*exp(-2*(t-x)) ;

int(f,x,0,t)

ans =

Thank you for quick response. The both variable x and t runs from 0 to 20 (say). For the value of x equal to 1, 4, 7 y(x) is equal to value 5 (say). y(x) is equal to 0 at other values of x. How do I insert this condition in above integral to calculate y(t)? Any advice is appreciated.
