How do I use sprintf to create a matrix of string and number arrays?
显示 更早的评论
Here is an example of the data I want to output using sprintf
a = {'abea','b','c'}
b=[1 2 3]
How do I get it so the output is out =
abea 1
b 2
c 3
the variables a and b may be any length.

In such cases, I use
>> v=[a;num2cell(b)]
v =
'abea' 'b' 'c'
[ 1] [2] [3]
>> sprintf('%s %d ',v{:})
ans =
abea 1 b 2 c 3
Following on Michael's answer, what if you try this:
clear
clc
a = {'abea','b','c'};
b = [1 2 3];
b_cell = num2cell(b);
OutCell = cell(size(a,2),1);
for k = 1:size(a,2)
OutCell{k} = sprintf('%s %s',a{k},num2str(b_cell{k}));
end
disp(OutCell)
which gives this:
'abea 1'
'b 2'
'c 3'

You don't need to use a loop:
sprintf('%s\t%d\n',v{:})
