Empty matrix:1-by-0是什么意思

Empty matrix:1-by-0是什么意思 matlab解不定方程 2x+2y=xy+7x=-2:6;y=-2:6;[x,y]=meshgrid(x,y);z=2*x+2*y;k=find(z==x*y+7);x(k)',y(k)'运行结果为ans =Empty matrix:1-by-0ans =Empty matrix:1-by-0请问怎么改 matlab find 查找矩阵元素坐标问题 前面运算后产生一个double型矩阵a=[.2032,0.0598,0.0072,...]运行下面代码：find(a==0.0072)ans =Empty matrix:1-by-0这是为什么啊,另外我将这个矩阵存成xls文件打开后,每一个 请问matlab里2-by-0 matrix是2*0矩阵还是0*2矩阵? Void CWYOPENGL View:DrawChuangshen(){//Materials of machine bedglCallList (m_material 2);//Push into the current matrix stackglPushMatrix();//Multiply the current matrix by a translator matrixglTranslatef(-160,0-175);//Multiply the current matrix by Matrix是什么意思1 matrix empty($_GET['page']) 0 :$_GET['page']-1 想问一下matrix::matrix(matrix &a)和matrix::matrix(matrix a)的区别如题Matrix::Matrix(Matrix tmp){y=tmp.y;x=tmp.x;M=new int *[y];for(int yy=0;yy fixed matrix是啥意思 MATLAB矩阵min已知matrix是一个二维矩阵,请问大虾：matrix=min(matrix,matrix.');是什么含义 empty empty Relation R is given by matrix（1 0 0 01 1 0 1 1 1 1 1 0 0 0 1）Is R an order?If yes,what its minimal,maximal,least,and greatestelements are? 英语翻译that is ,it is of the form where B=[P1,Pj1,...,Pjm] is an (m+1)-rowed square matrix and V is a matrix of m+1 rows and L-columns whose ith row is denoted by Vi. 线性代数,transposition是linear的吗?(0,1; 0,0)不能通过matrix转换成（0,0；1,0）所以很不肯定. LQMM指什麽,是,lead quality maturity matrix 英语翻译The call to TranslateTransform multiplies the Graphics object's existing world transformation matrix (rotation) by a translation matrix.
