str = num2str(A,format)
num2str
function converts numbers to their string representations. This function is useful for labeling and titling plots with numeric values.
str = num2str(a)
converts array A
into a string representation str
with roughly four digits of precision and an exponent if required.
str = num2str(a,precision
)
converts the array A
into a string representation str
with maximum precision specified by precision. Argument str = num2str(A,format
)
converts array A
using the supplied format. By default, this is '%11.4g'
, which signifies four significant digits in exponential or fixed-point notation, whichever is shorter. (See fprintf
for format string details).
num2str(pi)
is 3.142.
num2str(eps)
is 2.22e-16
.
num2str(magic(2))
produces the string matrix
1 3 4 2
fprintf
Write formatted data to file
int2str
Integer to string conversion
sprintf
Write formatted data to a string
