How di I make concise multiple parameter calls?

Is there an easy way of wrapping up multiple parameter calls via a single entity?

The parameters are a mix of floating point, integer and characters. I have:

formatspec=['\nExit conditions\n',...

'---------------\n',...

'Total products: %d\n',...

'Maximum fraction: %f\n',...

'Species: %d\n',...

'Product: %s\n',...

'Pressure [bar]: %f\n',...

'Ratio: %f\n\n'];

fprintf(formatspec,nproducts,mfrac,species,name,pcx,ofx);

I would like something on the lines of:

params=???nproducts,mfrac,species,name,pcx,ofx???;

fprintf(formatspec,params);

I see that you have tagged ThingSpeak in this post. Do you mean you are trying to pack multiple values in a single ThingSpeak field when you post data?

Yes, i believe so. Got an excellent answer from this valable community.

One way to do this is by storing the data (or params as you call them) in a cell array, see below for an example.

MyString = ['\nExit conditions\n',...
            '---------------\n',...
            'Total products:      %d\n',...
            'Maximum fraction:    %f\n',...
            'Species:             %d\n',...
            'Product:             %s\n',...
            'Pressure [bar]:      %f\n',...
            'Ratio:               %f\n\n'];

% store the params in a cell array
MyParams = {int32(3), pi, 10, "blabla", rand(1)*10, rand(1)}

MyParams = 1×6 cell array
    {[3]}    {[3.1416]}    {[10]}    {["blabla"]}    {[4.8122]}    {[0.0965]}

% print the data
fprintf(MyString,MyParams{:})

Exit conditions
---------------
Total products:      3
Maximum fraction:    3.141593
Species:             10
Product:             blabla
Pressure [bar]:      4.812172
Ratio:               0.096498

That's absolutely perfect. Curly brackets are a first for me!

Thank you very much Karim. :)
