When you index into the matrix A using only one subscript, MATLAB treats A as if its elements were strung out in a longcolumnvector, by going down the columns consecutively, as in: 16 5 9 ... 8 12 1 Tip:MATLAB is column major–linear indexing starts by going down the columns consecu...
cData = contourc(plane,[0 0]); startIndex = 1; if size(cData,2) > (cData(2,1)+1) startIndex = cData(2,1)+2; zData = iZ.*ones(1,cData(2,1)); plot3(hAxes,cData(1,2:(startIndex-1)),... cData(2,2:(startIndex-1)),zData,'k'); ...
Let us see an example related to find function, find function used to find indices and values of nonzero value. So in this example, we take a 3-by-3 matrix, and this matrix takes into a variable ‘Y’. So index 1 starts with row 1 and column one, and the next index value is ...

In this code, you first assign the upper left element in arr_2, at index (0, 0) to have a value of 10. Then you print arr_2 to verify that the appropriate value has changed. Finally, you print arr_1 and see that the value in the middle of the array has changed from 5 to 10...
