Matlab Convert Linear Index To Row Column

WebOct 7, 2010 · With linear indexing, we think of an array as starting with the (1,1) element, and, going down each row, stringing out the elements into a long column. Then we use the count into that column vector, which has length equal to numRows * numCols. Use sub2ind to make the transformation. linInds = sub2ind (size (A), [2 4], [3,2]) linInds = 10 8. Webind2sub. Subscripts from linear index. Syntax [I,J] = ind2sub(siz,IND) [I1,I2,I3,...,In] = ind2sub(siz,IND) Description. The ind2sub command determines the equivalent subscript values corresponding to a single index into an array.
