Hi, i am trying to delete NoValue from A without hardcoding so that i am only left with numbers and store them in Absorption vector but when i run the code it comes back exactly as it is, please help!!

  A =   20.0872
   16.1710
   20.6179
   17.9930
   18.6397
   16.5852
   22.5673
   21.0629
   19.8378
   19.9037
   20.2171
   21.6581
   21.2016
       NoValue
       NoValue
       NoValue
       NoValue
       NoValue
       NoValue
       NoValue
       NoValue
       NoValue

match = 'NoValue';
for Vec = 1:1:length(A)
    DeleteValues = strcmp(A,match);
    if DeleteValues > 0
        newStr = erase(A,match)
        Absorption = [newStr]
    end
end

The conditional of an if statement can only check one value at a time, yet deletedValues is a vector. For your if statement to work in the code you've written, you'd need to check one value at a time doing something like this.

if DeleteValues(Vec)
    ...

However, you don't need a for loop at all. Take advantage of MATLAB's ability to work with vectors.

  A =   [20.0872
   16.1710
   20.6179
   17.9930
   18.6397
   16.5852
   22.5673
   21.0629
   19.8378
   19.9037
   20.2171
   21.6581

   "NoValue"
   "NoValue"
   "NoValue"
   "NoValue"
   "NoValue"
   "NoValue"
   "NoValue"
   "NoValue"
   "NoValue"];

z = "NoValue";
DeleteValues = strcmp(A,z);
Absorption = A(~DeleteValues)

Actually, A is part of a long script that has different values and i just copied a few of this values. When i run the code you sent it gives me the 1st value only and i think it`s because NoValue doesn`t have " " in the script and i can`t edit the script because different set of values will be used to test my code. Is there a way to fix this?

[Cris LaPierre]

How do you get the values of A into MATLAB?

[WILLBES BANDA]

i make the call within my script (let`s say the name of the script that has values is DataValues.m then i`ll call DataValues in my script)

[Cris LaPierre]

Ok, but they have to get stored in a variable then. What are the dimensions and datatype of the variable they are stored in?

 "A"                 "B"              "C"               "D"                 "E"

    "19.053762"    "2820.8702"        NoValues         "78.248774"    "1.8150422e-05"

This is the script that has the values and its not complete here i just took a small portion, the dimensions are 289x6 in full

[Cris LaPierre]

We must be missing something. This script is just a text file of numbers. Running it shouldn't do anything. I actually get an error.

Is there some companion code that somehow captures these values? How do they get used in your script?
