Question:How to use the Chebyshev collocation method to solve the fourth order differential equation under the condition of u(±1)=u''(±1)=0?

I am reading Lloyd N. Trefethen's book "Spectral Methods in Matlab". For the fixed wall condition u(±1)=u'(±1）=0 of the fourth order equation, he used p=(1-x ^ 2) q (x) to convert the fixed wall...
