s = num2str(A) converts a numeric array into a character array that represents the numbers. The output format depends on the magnitudes of the original values. num2str is useful for labeling and titling plots with numeric values. example. s = num2str(A,precision) returns a character array that represents the numbers with the maximum number of ...
This operator automatically converts numeric values to strings when the other operands are strings. For example, plot a sine wave. Calculate the frequency of the wave and add a string representing that value in the title of the plot. X = linspace(0,2*pi); Y = sin(X); plot(X,Y) freq = 1/(2*pi); str = "Sine Wave, Frequency = " + freq + " Hz".
So i have created a function that returns a row vector of numbers, Example: [3, 6, 12, 1, 1, 3]. I want to write a new function that turns these numbers into letters. And in a form that i can call call it for any size set of results using a rule such as. 1 = A, 2 = B, 3 = C, 4 = D, etc. I see there is a num2str function but i dont really ...
The recommended way to convert text to double-precision values is to use the str2double function. It can convert character vectors, string arrays, and cell arrays of character vectors. For example, create a character vector using single quotes and convert it to the number it represents. X = str2double('3.1416') X =. 3.1416.
else. grade='F'. end. k = n + grade. disp (k) I need to write n and grade on the same line, but when this runs, instead of displaying the value of n, it displays a seemingly random symbol or number with the grade letter attached. example: If I enter 88 & 67 it makes k = 'MC', the values 100 & 20 make k = '<F'. Please help.
Open in MATLAB Online. Take a look at cell arraysof strings. Use the number directly as indices into a cell array, or convert using some scheme (like 100=1, 234=2, -12=3) first. Theme. Copy. num = [1 3 5 4 3 2 2 1] % num van be used as direct indices.
Description. A = count(str,pat) returns the number of occurrences of pat in str. If pat is an array containing multiple patterns, then count returns the sum of the occurrences of all elements of pat in str. count matches elements of pat in order, from left to right. Text segments in str can only be matched once. example.
Accepted Answer: Voss. Hi! I have trouble assigning a number to a letter combination in a table in Matlab, for instance x=0, f=10, s=1. the table looks something like this. x x f s. x f x s. x fs x ss. I want this to convert to a table like this: 0 0 10 1.
I'm trying to create a for loop that adds a number to a letter every time it loops. Here is my current code: for count=1:99; CM1=count; CM2=count+1; CM1X= ['X',CM1] CM2X= ['X',CM2] end. The problem that I am having is the X prints out fine, but the numbers print out as letters and then numbers and then characters.
I need to check to make sure that the user is only inputting a number from 1 to 14, and doing this involves checking if the user has put in random letters or something that isn't a number (e.g. "eihsgdf").
