Question

Start with the file loadkepler_template.m to create a function m-file named “loadkepler.m” that loads the Kepler orbital parameters contained in the text file gps_kepler.dat into a structure (the comments in the template file describe the contents of the data file). Then create a simple driver program named “test_kepler_LastName.m” that calls the function to load in the data file and also creates a bar chart of the ‘longitude of the ascending node’ parameter using satellite ID number as the x-axis (the call to the ‘bar’ function must, of course, use the created structure in the input arguments.

lEunction kepler loadkepler(filename) 1 Load Kepler parameters for modeling GPS orbits %LOADKEPLE % kepler LOADKEPLER ( filename ) . INPUT filename name of the text file ontaining the six columns of % parameters OUTPUT % kepler . svid- satellite identification numbers % kepler.meananomaly Mean anomalies (at reference time) in degrees % kepler.omega - longitudes of the ascending nodes for the (this is column 1 of the input file) (this is column 2 of the input file) satellites (at weekly epoch) in degrees (this is column 3 of the input file) % kepler . radius - orbit radii (semi-major axis) in meters (this is column 4 of the input file) % kepler . inclination = inclination angles of orbital planes of the satellites(in degrees) (this is column 5 of the input file) % kepler.reftime - reference times for the Kepler parameters for each satellite (in seconds relative to start of week) (this is column 6 of the input file) data load (filename)

Explanation / Answer

program to illustrate

#include<stdio.h>

int main(int argc,char* argv[])

{

    int counter;

    printf("Program Name Is: %s",argv[0]);

    if(argc==1)

      printf(" No Extra Command Line Argument Passed Other Than Program Name");

    if(argc>=2)

    {

        printf(" Number Of Arguments Passed: %d",argc);

        printf(" ----Following Are The Command Line Arguments Passed----");

        for(counter=0;counter<argc;counter++)

            printf(" argv[%d]: %s",counter,argv[counter]);

    }

    return 0;

}
