String To Variable Name Matlab How To Do These
VarName matlab.lang.makeValidName('123your.string(1)') PS: this will only modify your string so that it becomes a valid variable name, if it isn't already. The problem is that I have several variables in the for loop whose definition and value depend on the year suffix, that is they are constructed by combaining a letter (K,g, and so on) with the year number, so that they become K2006, g2006 and so on in the first iteration, K2007, g2007 and so on in the second iteration, and I have to consider also possible more years.Assume that you want to create a variable in Matlab whose name is contingent on factors that are unknown before the program runs. For example, you may want to attach a time or date stamp to the end of a variable name. You may also have variable names stored in a string or cell array that you want to instantiate as variables. The best way to accomplish these tasks in Matlab is to use the eval function. In the following examples, we’ll show you how to do these tasks.The problem is that you are hiding pesudo-indices in variable names.
You also want to use the variable name in its string format. The name sounds very irregular. You have to specify it manually.
In example 2, the variable names are stored as strings that are contained in a cell array. The values that will be saved in the variables are contained inside of a numeric array. A for loop is used to save each value in the variable named in each string.Notice in both of these examples that the eval function takes one string as an input and evaluates it as if it were a command typed into the command line. Usually, this string is broken up into static and variable content. Static content is placed inside of quotes, while variable content is outside of quotes and either entered as a variable name or enclosed within a num2str function.
fprintf(‘%d\n’,x) statement used to print variable x value.An assignment statement used for assigning the string to a variable.The statement in MATLAB is given by x='Hello' 10 is the value assigned to variable x. The assignment statement generally having the symbol = which is known as the assignment operator.The statement in MATLAB is given as x=10 Assign the value to a VariableAn assignment statement used for assigning a value to a variable. After reading this MATLAB Variable topic, you will understand how to create and manipulate Variable, and you will understand how to assign and display variable data in MATLAB.In MATLAB, an assignment statement automatically generates variable.
A variable name must start with a letter. fprintf(‘The x is %d The y is %d The r is %d\n’,x,y,r) statement to display variables x, y and z. 10, 32 and -12 are the values assign to variables x, y, and z respectively. fprintf(‘The x is %d\n’,x) statement to display variable x value.We can assign values to multiple variable in single statement.The statement in MATLAB is given by x = 10 y = 32 r = -12 Fprintf('The x is %d The y is %d The r is %d\n',x,y,r)Output The x is 10 The y is 32 The r is -12 fprintf(‘%s\n’,x) statement used to print variable x data.In MATLB, fprintf statement is used to print a variable data.
MATLAB Built-in function cannot be used as variable name. No spaces are allowed between characters. For example, AA, Aa, aA, and aa are the names of four different variables. MATLAB is case sensitive: it discriminates between uppercase and lowercase letters. Punctuation characters (e.g., period, comma, semicolon) are not allowed for defining variable names. A variable name can be made with letters, digits, and the underscore character.
