interpolating matrices between rows

I have the following matrix where the 1st column represents position x and 2nd column represents position y. The third column represents magnitude.Each row represents (x,y,magnitude) at a point. Is there any way to adaptively interpolate between the rows i,e interpolate using some function where there will be more points added beween certain points and less points added at others.

Thanks

Read about griddata and scatteredinterpolant functions.

No this doesnt work as there are some areas that does have any data.it seems to produce points all across the 2D frame.

You attach your data as a text file or mat file. Image snippet cannot be used to work.

Attached is the data. Thank you so much.
