Combining Single and Double Types
Combining single values with double values yields a single matrix. Note that 5.73*10^300 is
too big to be stored as a single, thus the conversion from double to single sets it to infinity. (The
class function used in this example returns the data type for the input value).
x = [single(4.5) single(-2.8) pi 5.73*10^300]
x =
4.5000
-2.8000
3.1416
Inf
class(x)
% Display the data type of x
ans =
single
Combining Integer and Double Types
Combining integer values with double values yields an integer matrix. Note that the fractional part
of pi is rounded to the nearest integer. (The int8 function used in this example converts its numeric
argument to an 8-bit integer).
x = [int8(21) int8(-22) int8(23) pi 45/6]
x =
21 -22
23
3
8
class(x)
ans =
int8
Combining Character and Double Types
Combining character values with double values yields a character matrix. MATLAB converts the
double elements in this example to their character equivalents:
x = ['A' 'B' 'C' 68 69 70]
x =
ABCDEF
class(x)
ans =
char
Combining Logical and Double Types
Combining logical values with double values yields a double matrix. MATLAB converts the
logical true and false elements in this example to double:
