1D heat transefer function [A,b,r] = fullyDev1dr(m,rout,mu,dpdx) fullyDev1dr CVFD coefficients for 1D fully developed flow in a pipe Synopsis: [A,b] = fullyDev1dr [A,b] = fullyDev1dr(m) [A,b] = fullyDev1dr(m,rout) [A,b] = fullyDev1dr(m,rout,mu) [A,b] = fullyDev1dr(m,rout,mu,dpdx)

说明：  希尔伯特黄变换，亲测有效，可放心使用，只是三维图运行会卡顿（三维图部分不确定正确）(Hilbert Huang transform, effective in pro test, can be used at ease, but the operation of 3D map will be stuck (the part of 3D map is uncertain))

some matlab tools. You can open it to have a look
