comment Using FindRoot with an interpolating function
What if I were to have more than one crossing and I still wanted to use FindRoot[...]. I noticed that FindRoot[...] doesn't allow for more than 2 guess values. I can use an {x,xmin,xstart,xend} but that didn't quite help.

@BoLe And to answer my own question, I just used the minimum and maximum x limits as my guess values. I think that does the trick.

@MichaelE2 I modified my code. I used Interpolation[Flatten[curve1,1],x]. This worked. I forgot that I needed to tell it to use x :P

@BoLe What if I don't know what the guess values should be and how many there should be?

@MichaelE2 I get what you mean now when you say x must be provided to the interpolation.

I still have an error message that suggests that the "function value is not a list of numbers" at x=0.2

So this displays numbers for all those values that are less than 0.5 the Maximum of mat? How can I change the number of decimal points?

Yes. That is what I meant.

@rm-rf Thank you for the encouragement and also the vital information that some journals perhaps would do their own color-B&W thingy!

@rm-rf Wow this seems ridiculously complicated enough to be a mini project!

@rm-rf I used ArrayPlot. All I get now is dark blobs. I am fine with that as it suits my needs. However, how do I mark individual points on this plot now?
