Matlab: Convert number to string (with zero-padding AND decimal precision) -

in matlab, num2str command converts numbers strings.

a format input allowed permits user number format,
including options zero-padding , precision.

is there way create string zero-pads number left
, permits specified decimal precision?

i'm not getting results demonstrate this:

examples of problem

input:
num2str(1.2,'%04f')
output:
1.200000

input:
num2str(1.2,'%04.f')
output:
0001

input:
num2str(1.2,'%04.2f')
output:
1.20

note zero-padding occurs in specific format.

desired behavior

input:
num2str(1.2,'%04.2f')
output:
0001.20

write:

num2str(1.2,'%07.2f') 

the number befor . total number of digits + ..

so 7.2 means: 7 total characters, them 2 after ..
