I can read the array into an interactive Matlab script using the prompt: F = input(' Enter the matrix name: ') This works fine in a main script. However, when I place this same command inside a supporting function file called by the main script, I get the following error message upon...
A is a matrix of size 1-by-13. Get size(A) ans = 1×2 1 13 Now create a string scalar by enclosing a piece of text in double quotes. Get A = "Hello, World!"; Check whether the scalar A of size 1-by-1 is also a matrix. Get TF = ismatrix(A) TF = logical 1 ...
How do I ask the user for some numerical values that are separated by a comma? For example "Enter the numbers, separated by a comma" Then the user would enter "1,2,3" and these numbers would go into a matrix Second question: There isn't a go to statement in Matlab, right?0...
Write a function that takes as input a matrix A and a vector x, and as out put gives the product y Ax by row Should use a loop The product y = A x of an m n matrix A times a vector x = ( x 1 ; x 2 ; : : : ; x n ) ...
Open in MATLAB Online Hi everyone, I have a problem with Inputting one matrix to other. I have one script where i create a array, and i would like to input the matrix "mixedsig" to other scrpit. When i run the second program my code is stopping in first if and i get "you must...
I want to build a model that uses fundamental inputs, for example, EPS PE, to get a target price for stocks. I would like to analyse many stocks at once so that I don't need to calculate them one by one. Can I inputs those data in matrix and get all outputs for...
把y的表达式改成下面就可以了 y=sqrt((442.1.*cos(x+4)-12.4).^2+(442.1.*sin(x+4)-174.9).^2);错误出现的原因，矩阵元素的幂，不等于矩阵的幂，矩阵的幂是 ^ 而矩阵元素的幂就是 .^ 请注意区别
Error using ==> mpower 这样的错误？其实，用 help mpower 查阅该函数的参考信息，可以知道mpower是矩阵幂函数（Matrix power），对应的符号就是“^”，而这个符号在楼主的表达式中。这里，要顺便做一点背景性的介绍：MATLAB中的运算符其实都有对应的函数，例如，“^”对应mpower，“*”对应mtimes，...
problem is most likely not the upper bounds but rather the number of dimensions. Without the specific error message it is hard to be sure. If you know one of the dimensions has a single element but MATLAB Coder does not you can use indexing to force the number of dimensions ...
