比如V=[1 2 3 4 5 6 7 8]想得到M=[1 2 3 4 5 6 7 8]可以这样:m=reshape(v,4,2),m=m.
The functionvect = reshape(A,sz)yields to turn a matrix into a row vector having specified sizesz. The matrix A’s cardinality must be the same as the size of the row vector. For example, if the given matrix A’s dimension is 5-by-2 then theszshould be 1-by-10. Examples In thi...
I plotted a vector H versus a vector r. its possible to have a plot 3D, i.e H as a function of x and y. r^2=x^2+y^2. Is there a direct method? Thank you for your suggestions !! Adam 댓글 수: 0 댓글을 달려면 로그인하십시...
Hello, I am trying to transform a line vector of length x² to a matrix size x*x. For example, ThemeCopy Vector = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16] and I want ThemeCopy Matrix = [ 1 5 9 13; 2 6 10 14; 3 7 11 15; 4 8 12 16] This is only an exa...
向量(Vector)也叫矢量,是一个m*1或1*n的矩阵。横向的叫行向量,纵向的叫列向量。注意:矩阵或矢量元素的起始索引(index),在数学领域一般是从1开始的,但在编程领域往往是从0开始。 利_刃 T800 10 矩阵的加法两个矩阵相加,这两个矩阵的行列数量必须相等,每个元素一一对应地相加就可以了。减法的计算,和加法是...

of Linear Algebra, which involves vectors and matrices. A vector is simply a list of numbers. A matrix is similar but contains multiple rows and columns of numbers. MATLAB contains a built-in function to reshape matrices that you can use to turn any matrix into a single row -- a vector...
我猜你的代码应该是 surf(Xp(i),Yp(i),Zp(i)) 出错了吧,当x和y为1*10的向量时,则构成了一个10*10的二维平面,因此此时z应该是一个10*10的矩阵,而不是标量或矢量,错误提示:Z must be a matrix, not a scalar or vector 就是这个意思。
