[英]variable number of arguments in ndgrid in MATLAB
I would like to generate a matrix of references. 我想生成一个参考矩阵。 This code works but I would like to use a variable size of set.
此代码有效,但我想使用可变大小的set。 I can't manage that... Thanks for helping !
我无法解决...谢谢您的帮助!
cpt = 1;
for ll = 1: 3
nb_rules = 5;
sets{cpt} = [1 : nb_rules];
cpt = cpt +1;
end
[x y z] = ndgrid(sets{:});% Here begins the trouble :
mat_ref = [x(:) y(:) z(:)];% what if size is not 3 ?
Use a cell
-array GRID
on the receiving end, to get a programmatic comma-separated list : 在接收端使用
cell
-array GRID
获得程序化的逗号分隔列表 :
N = numel(sets);
[GRID{1:N}] = ndgrid(sets{:});
mat_ref = reshape(cat(N+1,GRID{:}),[],N)
(No need to declare GRID = cell(..)
first.) (无需先声明
GRID = cell(..)
。)
