The screenshot above is my goal. This equation has two variables: k23 and Frequency. As you can see, the range of two variables going down from 0.1 to 0.001 and from 12 to 8.

This is the MATLAB plot I derived, frequency from the left to right can only keep increasing. How do I set it to decrease from left to right?

In addition, the variable k23 only increase by 0.05 steps. How do I set the steps to decades?

‘How do I set the steps to decades?’

Purely guessing, the logspace function could be appropriate, then set that axis to be logarithmic using the appropriate setting commands as described in XScale or YScale. You will likely have to experiment.

Thanks so much! Now it totally matches the plot that I expected!
