COnvert 3d matrix to 2D

I have a matrix of x=1200x30x410, i need to change it to 2D as x=3600x410. How to do that.?

it gives an error by using reshape that 'Product of known dimensions, 410, not divisible into total number of elements, 3672000'

The reshaped matrix has to be (36000 x 410).

x = rand(1200,30,410);              % Create Matrix
y = reshape(x,[],410);

You can reduce the first dimension afterwards, if necessary.

It doesn't work actually. Here's the x for example i need to change.

y should be equal to 6000x102

Please define ‘doesn’t work’.

It works for me:

D = load('matlab.mat');
x = D.x;
y = reshape(x, [], 102);

whos('y')

producing:

  Name         Size               Bytes  Class     Attributes

  y         6000x102            4896000  double
