Dear all.

I have problem about DCT function in matlab.

I want to use dct2 function to calculate data and resize it to 1X1.

For example, I have data matrix like

test=[3.2760 4.4200 1.9000];

Than, I use dct2 function to calculate dct and get data in 1X1.

testDCT = dct2(test,[1,1])

But result is return the first element.

testDCT = 3.2760

Am I wrong, or is it the limit of dct2 function?

Best.

Sorry, I give you wrong matrix. V V V

3.2760 does not look like the first element 5.5403 to me ?
