for i=1:N f(i) = 'f'+i; end gives an error in MatLab. What's the correct syntax to initialize an array with N strings of the pattern fi?
It seems like even this is not working:
for i=1:4 f(i) = 'f'; end

The + Operator The same + operator you use for adding two numbers can be used to concatenate two strings. You can also use += , where a += b is a shorthand for a = a + b .
Syntax: string new_string = string init + string add; This is the most easiest method for concatenation of two string. The + operator simply adds the two string and returns a concatenated string.
To concatenate a string to an int value, use the concatenation operator. Here is our int. int val = 3; Now, to concatenate a string, you need to declare a string and use the + operator.
You can concatenate strings using strcat. If you plan on concatenating numbers as strings, you must first use num2str to convert the numbers to strings.
Also, strings can't be stored in a vector or matrix, so f must be defined as a cell array, and must be indexed using { and } (instead of normal round brackets).
f = cell(N, 1); for i=1:N f{i} = strcat('f', num2str(i)); end If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
