#include<stdio.h>
#include<math.h>
int main(){
float x1,y1,x2,y2,vx,vy,len,x3,y3,size;
vx=x1-x2;
vy=y1-y2;
len=sqrt((vx*vx)+(vy*vy));
x3=vx/((len*size)+x1);
y3=vy/((len*size)+y1);
float temp1,temp2,angle;
temp1=y3-y1;
temp2=x3-x1;
angle=atan2(temp1,temp2)+1.57;
return 0;
}

You can either simply rewrite the algorithm in MATLAB, or create a MEX file and call the C code from MATLAB.
