Concatenation Examples

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:

```x = [true false false pi sqrt(7)]
x =
1.0000         0         0    3.1416    2.6458

class(x)
ans =
double
```
