writing your own linspace() function using nargin check, isnumeric, isscalar in matlab

main.m
function output_array = my_linspace(start_value, end_value, number_of_values)

% Check the number of input arguments
if nargin < 2
    error('At least two input arguments are required');
end

% Set default number of values
if nargin < 3
    number_of_values = 100;
end

% Check for numeric input arguments
if ~isnumeric(start_value) || ~isnumeric(end_value) || ~isnumeric(number_of_values)
    error('All input arguments must be numeric');
end

% Check for scalar input arguments
if ~isscalar(start_value) || ~isscalar(end_value) || ~isscalar(number_of_values)
    error('All input arguments must be scalar');
end

% Calculate delta between start and end values
delta = (end_value - start_value) / (number_of_values - 1);

% Calculate output array
output_array = start_value:delta:end_value;

end
