I am trying to make a matrix which has strings and numbers such as: a b c d 1 3 4 5 5 6 7 8 9 10 11 12 where a,b,c,d represent a word of sentence with no numerical value, how can I do that? 댓글 수: 1
Given a matrix, swap the 2nd & 3rd columns If a = [1 2 3 4; 1 2 3 4; 1 2 3 4; 1 2 3 4];then the result is ans = 1 3 2 4 1 3 2 4 1 3 2 4 1 3 2 4Perform a simple swap of the two middle columns. %%x = [1 2 3 4;1 2 3 4;1 2 3 4;1... ...

so I am trying to create a dynamic matrix and fill in information for each new loop. zeiten = zeros(j,3); zeiten(j,1) = einschwing; zeiten(j,2) = rtime; zeiten(j,3) = filenameString; But while the first 2 variables are double the last one is a string. So how can I write...
To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors. example plot3(X,Y,Z,LineSpec) creates the plot using the specified line style, marker, and color. example plot3(X1,Y1,Z1,...,Xn,Yn,Zn) ...

In MATLAB, when you access a slice of an array and assign it to a variable, MATLAB will make a copy of that portion of the array into your new variable. This means that when you assign values to the slice, the original array is not affected. Try out this example to help explain the...
