Your second input is not formatted correctly. It should be a 2 element vector, or a 2x3 numeric matrix. Based on where your semicolons are placed, you are creating a 3x2 element matrix instead (see here)
  • 2-by-3 matrix of the form [low_RGB_triplet; high_RGB_triplet]
Try this
app.TempEffect=imadjust(app.Modifies,[app.LowR, app.LowG, app.LowB; app.HighR, app.HighG, app.HighB]);

First, see DGM's reply. If would appear your image is not an RGB image, which means you will get an error.
However, here it appears the error is that you have not matched your brackets and parentheses correctly.
% Correct
a = ([1 2 3;4 5 6])
% your error
a = ([1 2 3;4 5 6))
Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

You need to pass in the correct arguments to imadjust, like two two-element vectors, not like what you did. Check the help.

You appear to be missing the ] corresponding to the [ that starts your second parameter.
