2. The area of a triangle ABC can be calculated by rea =- where|I I is the magnitude of the vector, AB is the distance vector from point A to point B and AC is the distance vector from point A to point C. Write a MATLAB user-defined function, [area] LASTNAMESTriArea (A, B, C), to calculate the area of the triangle using the equation above. The input A, B, and C are 1D arrays containing the XY or XYZ coordinates of the vertices of the triangle, e.g. A [2,3] or A = [1 2 0]. In your function, create -VecCross (vecl,vec2). The VecDist() function returns the distance vector between two points given by vertexl and vertex2. The VecCross function computes the cross product of two vectors given by vecl and vec2. You CANNOT use MATLAB built-in functions to calculate the cross product. Be sure to check for invalid inputs and display proper error/warning messages. Your code must include proper comment lines. Submit your User-Defined Function with Sub-Functions to BeachBoard.
