I want to ask how to check if a variable is table 1x8 or 8x1 of type logical? I know I can check the class of an array for logical like this:
strcmp(class(a),'logical')
I know I can get the size of table like this:
[h w] = size(a);
if(w==1 & h==8 | w==8 & h==1)
But what if table has more than 2 dimensions? How can I开发者_JS百科 get number of dimensions?
To get the number of dimensions, use ndims
numDimensions = ndims(a);
However, you can instead request size
to return a single output, which is an array [sizeX,sizeY,sizeZ,...]
, and check its length. Even better, you can use isvector
to test whether it's a 1-d array.
So you can write
if isvector(a) && length(a) == 8
disp('it''s a 1x8 or 8x1 array')
end
Finally, to test for logical, it's easier to write
islogical(a)
