WebFeb 5, 2015 · @Hello Matlab: Your explanation is inconsistent: "...to get the first row to a vector of 1x2..." and "assign those two value to [m,n]" means two quite different things. Do you want to obtain the vector of the first row, OR to get two variables m,n corresponding to the elements of the first row WebTo find array elements that meet a condition, use find in conjunction with a relational expression. For example, find(X<5) returns the linear indices to the elements in X that are less than 5. To directly find the elements in X that satisfy the condition X<5, use X(X<5).Avoid function calls like X(find(X<5)), which unnecessarily use find on a logical …
