The loop goes through each character, and should we encounter a space, we check to see if we have already encountered a space. If we have, just continue on in the loop. If we haven't, then concatenate a whitespace. Once we finally hit a non-space character, we simply just add those characters that are not spaces to this new string.Transfer functions are a frequency-domain representation of linear time-invariant systems. For instance, consider a continuous-time SISO dynamic system represented by the transfer function sys(s) = N(s)/D(s), where s = jw and N(s) and D(s) are called the numerator and denominator polynomials, respectively. The tf model object can represent SISO or MIMO transfer functions in continuous time or ...Accepted Answer: Stephen23. I am looking for any instances of two characters (e/d) being repeated in a row greater then or equal to 10. I just want to either print every line that this occurs to the command line or stop and print the location of the stop everytime it is detected. Basically I am trying to find when e and d show up over ten times ...example. tf = strcmp(s1,s2) compares s1 and s2 and returns 1 ( true) if the two are identical and 0 ( false ) otherwise. Text is considered identical if the size and content of each are the same. The return result tf is of data type logical. The input arguments can be any combination of string arrays, character vectors, and cell arrays of ...Since you posted your code I will make some corrections for you: Theme. Copy. n = input ('Enter a number:'); for sentence = 1:n % have the indexing go from 1 to n, not reverse. fprintf ('%d. Hello world!\n', sentence); % print the index, and a newline \n. end.

MATLAB strings are just arrays of characters. When you call ['cow','dog','cat'], you are forming 'cowdogcat' because [] concatenates arrays without any nesting. If you want nesting behaviour you can use cell arrays which are built using {}. s = strcat(s1,...,sN) horizontally concatenates the text in its input arguments. Each input argument can be a character array, a cell array of character vectors, or a string array. If any input is a string array, then the result is a string array. If any input is a cell array, and none are string arrays, then the result is a cell array of ...

Open in MATLAB Online. Hi Ebtesam, If you want to delete any character which is repeated three or more times in a row, you can substitute the @unique function in your cellfun () with a regexp that searches for 3+ character matches and replaces them with nothing: Theme. Copy. f = @ (s) regexprep (s, ' (\S)\1\1+', ''); cellfun (f,Input ...

Regular expressions provide a unique way to search a volume of text for a particular subset of characters within that text. Instead of looking for an exact character match as you would do with a function like strfind, regular expressions give you the ability to look for a particular pattern of characters.. For example, several ways of expressing a metric rate of …

Based on Abhinav's answer and some tests, I wrote a function which is ALWAYS faster than repmat ()! It uses the same parameters, except for the first parameter which must be a vector and not a matrix. function vec = repvec( vec, rows, cols ) %REPVEC Replicates a vector. % Replicates a vector rows times in dim1 and cols times in dim2.Each input argument can be a string array, a character vector, or a cell array of character vectors. If any input is a string array, then the output is a string array. ...

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. Get. X = linspace(0,2*pi); Y = sin(X); plot(X,Y) freq = 1/(2*pi); str = "Sine Wave, Frequency = " + freq + " Hz".Answer: Don't Do That. fprintf () the absolute value sign in one operation, and then fprintf () the numbers in a second operation. Or, repeat the ' %3d' part in the format as many times as you have numbers to print. Such as. Theme. Copy. fprintf ('| %3d %3d %3d %3d %3d ', T) if you were printing out 5 numbers across.For strings you can just write "abc" * 3, which works via StringOps and uses a StringBuffer behind the scenes.. For characters I think your solution is pretty reasonable, although char.toString * n is arguably clearer. Do you have any reason to suspect the List.fill version isn't efficient enough for your needs? You could write your own method that …If A has multiple rows, then compose returns str as a string array or cell array with the same number of rows.compose repeats formatSpec in each row of str, with formatted values from the corresponding row of A.. If the number of columns in A exceeds the number of operators in formatSpec, then compose repeats formatSpec as an additional column of str.Description. C = A + B adds arrays A and B by adding corresponding elements. If one input is a string array, then plus appends the corresponding elements as strings. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other.Regular expressions provide a unique way to search a volume of text for a particular subset of characters within that text.
