![]() ![]() C nchoosek (v,k) returns a matrix containing all possible combinations of the elements of vector v taken k at a time. This is the number of combinations of n items taken k at a time. operator in front of the exponentiation operator (i.e. b nchoosek (n,k) returns the binomial coefficient, defined as. Take special note that I assumed the function will element-wise square each elements in the input. Slope Field Generator for ODEs (slopefield) - File Exchange - MATLAB Central Slope Field Generator for ODEs (slopefield) 533 Downloads Updated From GitHub slopefield Draws the slope field of a first-order, univariate, ordinary differential equation. Let's say I want to create a function that squares every element in the input: > func = input('f(x) = ', 's') Take note that I had to concatenate the anonymous function string with the inputted function you provided with input. You'll want to take the input as a string by using the 's' option as the second parameter then use str2func to convert the string into an anonymous function: func = input('f(x) = ', 's') Bear in mind that the default method of input is to directly take the input and assign it as a variable where the input is assumed to be syntactically correct according to MATLAB rules. When using optimset, you can change the précision of the solution, and the parameter 0 in fsolve is the x0 for the solution.There's no need for the Symbolic Mathematics Toolbox here. In this case, y is a function and you can use y(5) to evaluate it value. You can defined a function using by writing: y = i*sqrt((((w^2*Mr*(Er))/isik_hizi^2)-(2*pi/lamdac)^2)) Divide code into manageable sections that can be run independently. Also, 2m is invalid syntax, if you want a variable called 2m, you can't, variable names have to start with letters, and if you meant 2 times m, then do 2m. ![]() ![]() Visit the Live Editor Gallery Create an Executable Notebook Create scripts that combine code, output, and formatted text. Do you know any Matlab syntax Aex is a single variable to the power of x, Aex is A multiplied by e to power of x. Constantino Carlos Reyes-Aldasoro about 6 hours ago. MATLAB Live Editor Create scripts that combine code, output, and formatted text in an executable notebook. syms u v eqns 2u + v 0, u - v 1 S solve (eqns, u v) S struct with fields: u: 1/3 v: -2/3. Solve a system of equations to return the solutions in a structure array. Mr= (1+yansima1)/(v*(1-yansima1)*sqrt((1/lamda0)^2-(1/lamdac)^2)) Plot the given channel capacity for Nakagami-m under worst case of fading for dual diversity under ora equation in MATLAB 1 Comment. The solve function returns a structure when you specify a single output argument and multiple outputs exist. S21 = gecis_genlik*cosd(gecis_faz)+i*gecis_genlik*sind(gecis_faz) %gecis_genlik= input('Genliği giriniz =') S11 = yansima_genlik*cosd(yansima_faz)+i*yansima_genlik*sind(yansima_faz) % yansima_genlik= input('Genliği giriniz =') I know other parameters and they are complex (w, Mr, isik_hizi, etc.) The direction field solver knows about trigonometric, logarithmic and exponential functions, but multiplication and evaluation must be entered explicitly ( 2x and sin (x), not 2x and sin x ). I have a equation but how I will find roots of function? For a much more sophisticated phase plane plotter, see the MATLAB plotter written by John C.
