Of course,we can use this method

>> matrix1=randi(10,3)
matrix1 =
     3     3     7
     8     1     6
     2     6     5
>> matrix2=randi(10,3)
matrix2 =
     7     7     8
     7    10     3
     7     3     2

Then the variable both matrix1 and matrix2 is random matrix.But I don't like this repetition work.If I'm in Mathematica,I just run

{matrix1, matrix2} = RandomInteger[10, {2, 3, 3}]

Then I get two 3*3 matrix. Matlab can conveniently to do such thing or is there any more elegant method?

There is no convenient way to do this in MATLAB.

You can create a variable and use mat2cell to break it into two cell locations. You need to assign that to a variable. Then you can use deal() to split the variable by taking advantage of comma list expansion. If you were doing this more than once you would want to write a function to do it.

在 MATLAB Online 中打开

iwant=randi(10,3,3,2)

I know this,I just don't know how to asign the two matrix to two variable.Such as you cannot use [a,b]=randi(10,3,3,2) to get two variable.

Why you want to assign them into two different variables? There is no necessity for this.. iwant(:,:,1) and iwant(:,:,2), this is the way you use where you want.
