how to change format of outputs?

2 views (last 30 days)
Hi
This is a continuation of my previous question
I have a vector name Z.mat(attached) which extracted from my simulation. I need to look for a specific value in it, 2.0785e+04.
Z vector format I guess is 「long e」,
cell number 5754 displaying 2.0785e+04 but when I clicked the cell its value is 2.083333000000000e+04
I can not find the value that I want because of the format difference I guess
I don't know how to fix the following code
survayline = 12*1000*tand(60);
% aspdepth=Y(Z==2.0785e+04);
aspdepth=Y(Z==20785e);
[aspdepth_sorted,aspdepth_order]=sort(aspdepth);
this code gives me
aspdepth []
aspdepth_order []
aspdepth_sorted []

Individual elements of an array or object do not have formats. Most data types do not have formats that can be controlled by the user (but datetime and duration objects can be controlled per variable)
When you talk about clicking on a cell you are talking about using the Variable Browser. You can go into Preferences to change the default format used by the variable browser.
Changing the format in the variable browser, or by using the format command, never affects the content of the variable or how it compares to something else.
Your problem is that the value you are searching for does not exist in the array.
You should look at ismembertol()

[~,idx] = min(abs(Z-2.0785e+04));
Z(idx)
ans =
20833.33
Your target value is not in your Z array.
