I\'m using python and numpy/scipy to do regex and stemming for a text processing application. But I want to开发者_JS百科 use some of R\'s statistical packages as well.
My brain has melted as I\'ve spent forever on this problem. I need to offset a cube from the origin by two in both the x and y direction however keep the one point perspective like I\'m looking strai
Let\'s said you have a 1D matrix a = rand(1,5); [sa i] = sort(a); then sa and a(i) are the same. However, if the size of the matrix increases
I\'m doing a simple 2d game, with using opengl ortho view, with triangles as a sprites. The problem is, that absolutely the same game code works perfect on my mac simulator, but when I launch the gam
I have this in matlab A=34; for i =1:1:6 A = A + 1; t1=fix(A/(2*32)); t2=fix((A-(t1*64))/(32)); t3=fix(((A-(t1*64)) - (t2*32))/(16));
For example I have function that creates matrix 2x2 : [1 2; 3 4] I have开发者_如何转开发 such simple function:
Imagine a gravity/rotation sensor of iPhone that for each attitude of the device provides a gravity vector (Vg) and a current 3x3 rotation matrix (M0). Such as:
Given 2 matrix A, B with the same dimension, M(x, y) = |开发者_StackOverflowA(x, y).*A(x, y)A(x, y).*B(x, y)|
I have an M-by-M-by-N matrix, which is a concatenation of N M-by-M matrices. I want to reduce this matrix to an M-by-N matrix by taking the diagonals of each M-by-M submatrix and concatenating them to
My problem, removing the specific purpose,seems like this: how to transform a combination like this: first use combn(letters[1:4], 2) to calculate the combination
