Operands to the || and && operators must be convertible to logical scalar values.

I want to find how many pixels are on the image between 150 and 200 gray values. So I created a code, but I'm receiving this error.
% extracted rows from the column
ext_rows = imgray(start_row:end_row,start_column:end_column);
whitePixels=ext_rows((150<ext_rows) && (ext_rows<200));
numberWhitePixels=numel(whitePixels);
I'm receiving this error.
Operands to the || and && operators must be convertible to logical scalar values.
How can I solve this error? Could you please write down correct code here?

Use & instead for element-wise and (or | for element-wise or):
whitePixels=ext_rows((150<ext_rows) & (ext_rows<200));
