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
