Hi,

I have two tables (1) Data table, (2) Spec Table(includes lower & upper limit). First row shows Variable name (A,B,C,D,E) for the same I have the spec table. Here, NA represents spec not defined,and if a variable value is not double just report (NA). I want to do

1. If the status is Fail, then check the corresponding variables (their value) is within the spec or not, if it is in the spec then report OK, else report Out.My output table is shown.Many thanks in advance.

Data table:

Status    A    B    C    D            E
Success    -0.5    9    2    Positive    12
Fail    7    11    23    Positive    3
Success    1    9    18    Deflect            6
Success    1.3    3    15    Positive    12
Fail    -6    6    -1    Negative    1
Success    0.8    4    11    Positive    25
Fail    3    9    26    Positive    30

Spec table:

  Lower  Upper
A  -1.5  1.5
B  NA  NA
C  0  20
E  5  25
Output:
A  B  C  D  E
OK  NA  OK  NA  OK
Out  NA  Out  NA  Out
OK  NA  OK  NA  OK
OK  NA  OK  NA  OK
Out  NA  Out  NA  Out
OK  NA  OK  NA  OK
Out  NA  Out  NA  Out

I suggest you convert the above tables first to actual MATLAB table variables.
Use categorical to tell the Status column is from a finite set of Success of Fail.
Finally use logical indexing with the categorical variable (to dig into only rows that are Success or Fail). You can use logical indexing to perform relational operators (Such as <, >, >= etc.) to find if the Spec table is then satisfied or not.
Take a look at this example that explains a similar workflow.
