Using fprintf with a combination of a double-array and a cell-array

Question

Using fprintf I want to produce an output that looks like this:

names abc and numbers 1
names def and numbers 2
names ghi and numbers 3

This is the code I tried using to achieve this:

names= {'abc','def','ghi'}
numbers = [1 2 3];
fprintf('names %s and numbers %2.2f \n',names{1:3},numbers)

unfortunatly the output it produces looks like this:

names abc and numbers 100.00
names ef and numbers 103.00
names hi and numbers 1.00
names and number

Does anyone know how to solve this issue? Or is it even possible to combine fprintf with cell-arrays? Thanks in advance

Answer 1

Take a look at what you are passing to fprintf, it is simply in the wrong order, and numbers creates one parameter not three individual:

>> names{1:3},numbers

ans =

abc


ans =

def


ans =

ghi


numbers =

     1     2     3

Instead use:

C=names
C(2,:)=num2cell(numbers)
fprintf('names %s and numbers %2.2f \n',C{:})

If you typie in C{:} you will see the individual parameters in order:

>> fprintf('names %s and numbers %2.2f \n',C{:})
names abc and numbers 1.00 
names def and numbers 2.00 
names ghi and numbers 3.00 

>> C{:}

ans =

abc


ans =

     1


ans =

def


ans =

     2


ans =

ghi


ans =

     3
