strcat

Concatenating character arrays

Usage

strcat(s1, s2, ..., sn)

• Each of s1, s2, ..., sn is either a row vector or a matrix. They must be arrays of numerical values or characters.
• If s1, s2, ..., sn are matrices, they must have same heights. If any one of the inputs is a row vector, it will be expanded vertically to matches the heights of the matrix inputs.
• It returns a character matrix by concatenating s1, s2, ..., sn horizontally.

Difference With MATLAB

• MATLAB removes trailing white-space and newline characters of s1, s2, ..., sn, whereas SIMO does not.

Examples

• The trailing space after the car emoji will be preserved after concatenating. This is different from MATLAB, in which trailing white spaces are ignored.

Input

a = 'I love 🚙 '
b = 'and you!'
strcat(a,b)

Output

ans = 
I love 🚙 and you!

• The row vectors a and b are expanded vertically to match the height of c.

Input

a = 'I love ';
b = 'and you!';
c = ['🚙 ';'🚚 ']; 
strcat(a,c,b)

Output

ans = 
I love 🚙 and you!
I love 🚚 and you!

• In this example, strcat converts matrices of double values to character arrays before performing catenation.

Input

% Array sizes
m1=3; n1=5;
m2=3; n2=6;
% Double arrays
dbl1=randi(100,m1,n1)
dbl2=randi(100,m2,n2)
% The double arrays are converted to characters
% and then catenated.
cat=strcat(dbl1, dbl2)

Output

dbl1 = 
 52.000   40.000   57.000   33.000   29.000
 21.000   66.000   6.0000   67.000   38.000
 26.000   11.000   92.000   43.000   39.000

dbl2 = 
 45.000   83.000   71.000   89.000   9.0000   99.000
 15.000   74.000   99.000   87.000   98.000   2.0000
 7.0000   32.000   75.000   59.000   18.000   61.000
