how to fill an array with data from intercalated/multiple range columns

Hi,

I have a matrix A, with dimensions 4000*50. I would like to select lines 1 to 2000 (1st dimension) and columns 1 to 40 and 42 to 50 to fill an array. Is there any operation/method that allows me to do it at once, avoiding the need of the function "cat". I know I can select lines 1 to 2000 and all columns to fill my array A1:

A1=A(1:2000,:)

However, I am unsure if this method/operation support intercalations, as per my requirements. Any help is appreciated.

I thank you in advance,

Best regards,

A1 = A(1:2000,[1:40,42:50]);
