x = input(prompt) displays the text in prompt and waits for the user to input a value and press the Return key. The user can enter expressions, like pi/4 or rand(3), and can use variables in the workspace.

ais=input('Give me a letter you would like converted to a number: ', 's') alphabet=[ 'a' , 'b' , 'c' , 'd' , 'e' , 'f' , 'g' , 'h' , 'i' , 'j' , 'k' , 'l' , 'm' , 'n' , 'o' , 'p' , 'q' , 'r' , 's' , 't' , 'u' , 'v' , 'w' , 'x' , 'y' , 'z' ]

str = string(A) converts the input array to a string array. For instance, if A is numeric vector [1 20 300], str is a string array of the same size, ["1" "20" "300"].

Users can enter scalar or vector values into inputdlg text edit fields. MATLAB ® stores the input as a cell array of character vectors. Convert a member of the input cell array to a number, using str2num.

Name of input variable to validate, specified as a string scalar or character vector. If you specify an empty character vector '' or the <missing> string, then the validatestring function ignores the varName input.

Input array, specified as a scalar, vector, matrix, or multidimensional array. A can be any data type.

x = input(prompt) displays the text in prompt and waits for the user to input a value and press the Return key. The user can enter expressions, like pi/4 or rand(3), and can use variables in the workspace.

Oct 20, 2011 · I am trying to make a function: function [y]=my_function(A,B,C) where A is a string and B and C are just numbers. If someone enters 'yes' for A then a number for B and C I want it to do one...

May 13, 2014 · Once you have the user's input string and have created the variable name, you can use the eval function to access that variable.

MATLAB provides several functions to search for, replace, or extract text in string arrays and character vectors. Build Pattern Expressions; Regular Expressions; Lookahead Assertions in Regular Expressions; Tokens in Regular Expressions; Dynamic Regular Expressions; Unicode and ASCII Values. MATLAB stores all characters as Unicode characters.
