If you have the Aerospace toolbox..

try

convlength

http://www.mathworks.com/help/aerotbx/ug/convlength.html

or mapping toolbox

 distdim

http://www.mathworks.com/help/map/ref/distdim.html;jsessionid=4fcb75cc3c10d05d079da412f9df

Otherwise you might want to write your own simple script for the same if there is nothing in File Exchange

Some given here:

There can be many solutions for this, smaller one also, but for a beginner level, this will sure work for you.

d= input('Enter the Input Distance: ');
  i= input('Enter the input Units(cm,in,ft): ');
  o= input('Enter output units to convert to(cm,in,ft): ');
  switch i
      case 'cm'
          if o=='in'
              x=d/2.54;
          else
              if o=='ft'
                  x=d/30.48;
              else 
                  if o=='cm'
                      x=d;
                  end
              end
          end
      case 'in'
          if o=='in'
              x=d;
          else
              if o=='ft'
                  x=d/12;
              else 
                  if o=='cm'
                      x=2.54*d;
                  end
              end
          end
        case 'ft'
            if o=='in'
                x=d*12;
            else
                if o=='ft'
                    x=d;
                else 
                    if o=='cm'
                        x=d*30.48;
                    end
                end
            end
            str = fprintf('%d %s = %d %s',d,i,x,o);
    otherwise
        disp('wrong input');
    end

In MATLAB a "scalar" is a vector with just one element, for example [1] is the same as 1

here's a sneaky way to separate all the digits of a scalar into columns of a vector

nc=1010; %my scalar value 
nv=num2str(n)-'0' %my vector
