WebJan 12, 2024 · This is the way Matlab show the expression, but you can't write it like that. You should do something like X=NaN + NaN*i (while i is not a variable in your workspace). If you want to check if there is even one NAN element in X you should use any: if any (isnan (X)) disp ('values...'); end – Adiel Jan 11, 2024 at 7:41 WebTo integrate a mathematical function from -inf to inf in MATLAB, I am using from trapz but i am finding it difficult as the variable like d (X), X has to be like ( -1000,1000,2000), but since...

WebNov 26, 2012 · Single loops are now very fast in Matlab IF you set your problem up so you can operate on the columns of a matrix (as opposed to the rows), since these elements are allocated sequentially in memory. Now, let us assume that there is only one Inf per column. WebInverse of a matrix in MATLAB is calculated using the inv function. Inverse of a matrix A is given by inv (A). Example Create a script file and type the following code − Live Demo a = [ 1 2 3; 2 3 4; 1 2 5] inv(a) When you run the file, it displays the following result − WebMATLAB Commands – 4 Special Variables and Constants ans Most recent answer. eps Accuracy of floating-point precision. i,j The imaginary unit -1.
