In this tutorial, we will write a go language program to add two matrices. A matrix is a collection of numbers that are arranged in rows and columns, which is a two-dimensional array. Go Language Program To Add Two Matrices Let us now look at a go language program to add two matrices...
于是,我就在我自己的xll_quantlib项目中,把QuantLib的矩阵运算,写成一个MatrixUtility的Add-in。下图中便是把QuantLib中的PseudoSqrt()函数封包在我DPseudoSqrt()的函数之中,后者可以在Add-in中叫用。注意一些编译选项的设定,如前文(九十三)所提,把相关的hpp、lib加入,然后编译出MatrixUtility.xll。 然后把这个...

It is also possible to convert a quaternion to or from a 3x3 array of floats representing a rotation matrix, or an array of N quaternions to or from an Nx3x3 array of floats representing N rotation matrices, using as_rotation_matrix and from_rotation_matrix. Similar conversions are possible...
