Num2Str and concatenating help

I need to concatenate a cell array where 2 columns are strings and one is numeric. I tried doing this by first changing the numeric to num2str then to char but num2str makes it 4xn, n being how many digits the number has, which does not fit in with the dimentions of the rest(4x1). How can I fit this?

This is all of my code by the way:

        function varargout = ymv2102_final(varargin)
      % YMV2102_FINAL MATLAB code for ymv2102_final.fig
      %      YMV2102_FINAL, by itself, creates a new YMV2102_FINAL or raises the existing
      %      singleton*.
      %
      %      H = YMV2102_FINAL returns the handle to a new YMV2102_FINAL or the handle to
      %      the existing singleton*.
      %
      %      YMV2102_FINAL('CALLBACK',hObject,eventData,handles,...) calls the local
      %      function named CALLBACK in YMV2102_FINAL.M with the given input arguments.
      %
      %      YMV2102_FINAL('Property','Value',...) creates a new YMV2102_FINAL or raises the
      %      existing singleton*.  Starting from the left, property value pairs are
      %      applied to the GUI before ymv2102_final_OpeningFcn gets called.  An
      %      unrecognized property name or invalid value makes property application
      %      stop.  All inputs are passed to ymv2102_final_OpeningFcn via varargin.
      %
      %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
      %      instance to run (singleton)".

[Fangjun Jiang]

To make your question effective, I would suggest you come up with a small set of example data and show the relevant part of your code. Your description of the problem certainly sounds like it can be easily abstracted. Don't just dump all your code.

Answer 1

[Fangjun Jiang]

a={'abc','ef',34;'AB','CDEFG',45};
b=a.';
c=sprintf('%s%s%d\n',b{:})

Answer 2

[Walter Roberson]

Each place that you use num2str(), change the argument to a column vector. For example, change

total_cost=num2str(total);

to

total_cost=num2str(total(:));
