+# EKF
+
+Executes TinyEKF as shows by [You Chong's GPS example](http://www.mathworks.com/matlabcentral/fileexchange/31487-extended-kalman-filter-ekf--for-gps)
+
+In order to be compatible with the stdin/stdout model of serverless, the input and output files are binary concatenations of various C structs.
+
+See `main()` in `runtime/tests/TinyEKF/extras/c/gps_ekf_fn.c` for specifics.
+
+This test executes multiple iterations, comparing the binary result against a known memoized result stored at `expected_result.dat`.
