Hello! I need to generate a string with the numbers 1:999.
I wrote these lines of code:
row_number = 1:999;
column_number = row_number.';
conversion_column_number = num2str(column_number);
I want to eliminate the two spaces that are created before the numbers 1:9 and the space that is created between the numbers 10:99 in conversion_column_number. Is there a solution to this problem?

Hi, Alberto
Please try the following code:
row_number = 1:999;
column_number = row_number.';
conversion_column_number = string(column_number);
This has the following output:

According to MATLAB documentation, the function num2str() converts the input array to a character array and MATALB makes sure that each element in a character array is of the same size, which is why you're getting the spaces.

Hi!
I understand that you want to convert 'column_number' to a string without extra spaces.
You can use the 'string' function instead of 'num2str' here.
row_number = 1:999;
column_number = row_number.';
conversion_column_number = string(column_number);
Alternatively, you can try with this.
row_number = 1:999;
column_number = row_number.';
conversion_column_number = "" + column_number;
For more information you can refer the following documentation: https://www.mathworks.com/help/matlab/ref/string.html
