extracted_pixels = YourArray( sub2ind( size(YourArray), RowList, ColumnList ) );

It does not have to be in matrix form, but you did say the pixels were in row, column form which does tend to imply matrix form, as otherwise you would only have one index.
The above code works for multiple indices. Example,
extracted_pixels = YourArray( sub2ind( size(YourArray), [2 7 8], [1 1 4] ) )
would extract (2,1) and (7,1) and (8,4)

Can anyone help me form a feature vector for every pixel,based on the intensity,color,orientation and scale??
