deleting multiple rows in a matrix

how can i completely remove the first 110 rows and the last 70 in a (500*1) matrix? for example is this correct? A(1:110, : ) = [ ] A (430:500, : ) = [ ] Is there a way to combine the two?

A([1:110 end-69:end],:) = [];

(Also, note that 430:500 is 71 elements, not 70.)

what if instead I have to completely remove the first 110 rows and the last one in a matrix (500*1)? A([1:110 end-1],:) = []; or A([1:110 end],:) = [];

Use "end" to refer to the last row. "end-1" refers to the next-to-last row.
