Thread-topic: linear fit pulse response MATLAB code Colleagues, I’m wondering if there is a public version of MATLAB (or other) code which implements the linear fit pulse response equations set forth in 85. The 1D Poisson equation is assumed to have the form -u''(x) = f(x), for a x. The code, in full or in part, is not a translation or a copy of any of the existing codes. I have this system of linear equations: $$A= \begin{bmatrix} 2 & 0 & 1 \\ 0 & 1 & -1 \\ 1 & 1 & 1 \end{bmatrix}$$ $$b= \begin{bmatrix} 3 \\ 0 \\ 3 \end{bmatrix}$$ I Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn.
