2024 Matlab string concatenation

Algorithms. When concatenating an empty array to a nonempty array, cat omits the empty array in the output. For example, cat(2,[1 2],[]) returns the row vector [1 2]. If all input arguments are empty and have compatible sizes, then cat returns an empty array whose size is equal to the output size as when the inputs are nonempty. For example, …. Paul battaglia

The reason is in strcat's documentation:. For character array inputs, strcat removes trailing ASCII white-space characters: space, tab, vertical tab, newline, carriage return, and form-feed. To preserve trailing spaces when concatenating character arrays, use horizontal array concatenation, [s1, s2, ..., sN]. For cell array inputs, strcat does not …Concatenation of Matlab strings. 1.

This example shows how to concatenate structure arrays using the [] operator. To concatenate structures, they must have the same set of fields, but the fields do not need to contain the same sizes or types of data. Create scalar (1-by-1) structure arrays struct1 and struct2, each with fields a and b: struct1.a = 'first' ; You can combine strings horizontally in either of the following ways −. Using the MATLAB concatenation operator, [] and separating the input strings with a comma or a space. This method preserves any trailing spaces in the input arrays.
