I need help with my MATLAB script, as I don't understand how to correct the error message that I'm getting.   The error message is: >> BioOpsA1cgptAttempt1 Unrecognized function or variable 'FluorLifeTime_Data01'. Error in BioOpsA1cgptAttempt1 (line 5) Taxis = FluorLifeTime_Data01(:, 1);   My script is given below:   % a. Load the dataset load("FluorLifeTime_Data01.mat");   % b. Extract photon arrival times and fluorescence photon counts Taxis = FluorLifeTime_Data01(:, 1); FCounts = FluorLifeTime_Data01(:, 2);   % Initial guess for parameters initial_params = [1, 1];   % Call fminsearch to optimize the model optimal_params = fminsearch(@(params) FLmodel(params, Taxis, FCounts), initial_params);   % Extract optimized parameters A_opt = optimal_params(1); tau_opt = optimal_params(2);   fprintf('Optimized Parameters: A = %.2f, tau = %.2f\n', A_opt, tau_opt);   % Create a time vector for the fitted curve T_fit = linspace(min(Taxis), max(Taxis), 1000);   % Generate the fitted curve using optimized parameters F_fit = A_opt * exp(-T_fit / tau_opt);   % Create a figure figure;   % Subplot 1: Raw data and fitted curve subplot(2, 1, 1); plot(Taxis, FCounts, 'bo', T_fit, F_fit, 'r-', 'LineWidth', 2); xlabel('Time (Taxis)'); ylabel('Fluorescence Counts'); title('Raw Data and Fitted Curve');   % Subplot 2: Residuals subplot(2, 1, 2); residuals = FCounts - A_opt * exp(-Taxis / tau_opt); plot(Taxis, residuals, 'ko'); xlabel('Time (Taxis)'); ylabel('Residuals'); title('Residuals');   % Adjust subplot spacing subplot(2, 1, 1);     As well as the function script:   function error = FLmodel(params, Taxis, FCounts) % Extract model parameters A = params(1); tau = params(2);   % Model function model = A * exp(-Taxis / tau);   % Calculate error (objective function) error = sum((model - FCounts).^2); end     I have the .mat file in multiple places in my files, so I don't know why its having trouble. Is it a syntax mistake; is my matlab not loading files properly? Thank you in advance!

Please use MATLAB

write a python code named get_total_cases() takes the a 2D-list (similar to database) and an integer x from this  set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases)

Write the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result.   - If mystr has at least one instance of adjacent characters being equal, return True   - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error")   if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie")   if not (has_adjacent_repeats("Hanoverr") is True): print("error")

Assume that the following user-defined function is available in Matlab:   function [d, e] = someFunction(a, b, c)        d = 2 * b * c;        e = 3 * d; end   If the following Matlab expression    >> [varA, varB] = someFunction(2, 3, -2);   gets executed in Command Window (and the program control flow is transferred to the someFunction function), which value gets assigned to variable a inside someFunction?     2     -2     3     No value will be assigned to that variable

Using Python

Assume (or you can create it) a function for detecting prime numbers is created. Then, write a script file in MATLAB that will call that function for all number between 600 and 999, find the twin primes, safe primes, sexy primes, and Mersenne primes and "good" friends. Note: I already have the function (isprime(num)). I want the script file following the above conditions.
