Hi All,
I have two arrays that contain the row and column indices for values in a thrid array. Is there a way to compare the two matrices containg the indices and extract the indices that are common to both arrays.
Here is a simple example. I have two arrays: RowCol1 & RowCol2
RowCol1 = [17,487504; 17,487591; 17,487596; 17,487605; 17,487617]
RowCol2 = [16,113; 16,116; 16,244; 17,487591; 17,487596; 17,487605; 16,278]
I want to compare these two arrays and extract the row and column values that are common to both i.e. I want to extract
[17,487591; 17,487596; 17,487605;]
I appreciate any help.
thanks

RowCol1 = [17.487504; 17.487591; 17.487596; 17.487605; 17.487617];
RowCol2 = [16.113; 16.116; 16.244; 17.487591; 17.487596; 17.487605; 16.278];
out = intersect(RowCol1,RowCol2)
The default format doesn't show the differences, but those are the values you wanted.
