Question

XY(:,i)=R*XYw(:,i)+T.'; Error using ==> mtimes Inner matrix dimensions must agree 这个语句那错了啊

Answer 1

在MATLAB中如果你哪个不懂的话可以用 help,如 help mitimes,结果是 help mtimes
* Matrix multiply.
X*Y is the matrix product of X and Y.Any scalar (a 1-by-1 matrix)
may multiply anything.Otherwise,the number of columns of X must
equal the number of rows of Y.
C = MTIMES(A,B) is called for the syntax 'A * B' when A or B is an
object.
所以应该是你的两个矩阵的行列数不能满足乘法法则,
