type
edit sendmail
and look into
function toSend = formatText(msgText)
there you can find the line
maxLineLength = 75;
which you can set to inf
you could also change the sendmail function and add another variable by changing the head of the function sendmail and formatText to e.g.
function sendmail(to,subject,theMessage,attachments,maxChars)
if nargin<5 || isempty(maxChars) || ~isnumeric(maxChars) || maxChars<=0
maxChars=75; % define some default
else
maxChars=ceil(maxChars); % to avoid non integer input
end
% ...
body = formatText(theMessage,maxChars);
% ...
function toSend = formatText(msgText,maxChars)
% ...
maxLineLength = maxChars;
% ...
then you would be more flexible in amount of character wrapping
