Find Function In Mat

All the outputs the actual values related to are together called the range.

Find function in mat.

If none are found find returns an empty 0 by 1 matrix. To find array elements that meet a condition use find in conjunction with a relational expression. A function relates inputs to outputs. In matlab i use the find function to get the indices of a vector and then copy these to other variables.

Indices find x k or indices find x k first returns at most the first k indices corresponding to the nonzero entries of x. In general find x regards x as x which is the long column vector formed by concatenating the columns of x. A idx and b are vectors. Introduction to find function matlab.

If it finds none the function will return an empty matrix. A function takes elements from a set the domain and relates them to elements in a set the codomain. Matlab provides its user with a basket of functions in this article we will understand a powerful function called find. Find the vertex of the function if it s quadratic.

If you re working with a straight line or any function with a polynomial of an odd number such as f x 6x 3 2x 7 you can skip this step. 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 matrix. For example find x 5 returns the linear indices to the elements in x that are less than 5. Every element in the domain is included and.

I am trying to convert matlab code to c. But if you re working with a parabola or any equation where the x coordinate is squared or raised to an even power you ll need to plot the vertex.
