lapack sgetrs tutorial

I have a problem to solving system linear equation Ax=b using lapack. I am planned to use sgetrs subroutine in lapack to solving system linear equation Ax=b. sgetrs descriptions is a subroutine to Solves a system of linear equations with an LU-factored square coefficient matrix, with multiple right-hand sides. So, we need to process our

gausswin source code

I want to create gaussian window program in C/C++. I have checked at Matlab and they give gausswin function to create gaussian window. I have checked gausswin Matlab source code and convert that code to C/C++. The coefficients of a Gaussian window are computed from the following equation: where –(N – 1)/2 ≤ n ≤ (N – 1)/2 and α is inversely proportional

VirtualBox Install El Capitan

I am very interesting to install Mac OS in my desktop computer using VirtualBox. I have created steps how to install Mac OS in VirtualBox. But, you need existing Mac OS to create bootable Mac OS. I want to install Mac El Capitan (10.11) in my VirtualBox. I dont have fast internet connection. So, I

Matlab Data Precision Problem

I have created a simple computation using Matlab using command : [crayon-5f0060a543279062642051/] Nothing wrong with the result. But, try to change data precision format and try to retype command above. we will get Matlab data precision problem from this simple computation. [crayon-5f0060a543280981056033/] We get the wrong result. I hope can get 71.5000 from above command.
