Grid search for optimization method in matlab

[jasonlawps]

I am currently dealing with the paper Optimal Signal Processing Frequency-Stepped CW Radar Data I need to find the best combination of t to get minimum of J. Here is the procedure to find the t:

1. I have 2 number of t: t=[t1 t2]. t will start with any value but greater than zero.
2. t will insert to an algorithm to find Jminimum
3. t2 is held constant while the minimum of J is found along the t1 dimension.
4. t1 is held constant at the value previously found while the minimum of J is found along the t2 dimension.
5. 3 and 4 are repeated until the time delay values are no longer updated.
   My question is: how to implant this procedure into my code?

Below is my code:
