I'm trying to get the string of names that i received from my previous statement , to write over to my excel spreadsheet but nothing is happening when i press run. I'm unsure what to do next?

SystThresh=90 ;

SystThresh1=120;

DiaThresh=60;

DiaThresh1=80;

isOK=(Systolic > SystThresh & Systolic < SystThresh1 & Diastolic > DiaThresh & Diastolic < DiaThresh1);

fprintf('%s is ideal\n',Names(isOK));

xlswrite('BPResults.xlsx',{'Ideal'});

xlswrite('BPResults.xlsx',Names(isOK),'Sheet1','A2');

What data type is Names ?

What is the output of

nnz(isOK)

[Justin Howard]

Names is a string, and isOK is stored as a logical array.

[Walter Roberson]

When you say that Names is a string, do you mean that it is a string() array and indexing it with isOK is intended to return smaller string() array? Or do you mean that Names is a character vector, in which case indexing it with isOK would be choosing individual characters out of the character vector? Or do you mean that it is a cell array of character vectors?

What output is showing up for

fprintf('%s is ideal\n',Names(isOK));

?
