For 3D plotting of curves, you should use the plot3 command. Plotting based on row/column names, rather than row/column indices is harder.īy the way, plot(x,y,z) is not a valid command. Plot3(i, j, data(i,j)) % Plot the data at 'c1' and 'r3' locationīut again, this is also a somewhat convoluted way of working with numerical data. J = find(strcmp(colNames, 'c1')) % Column index For example, M = ĭata = rand(3,3) % A random matrix with 3 rows and 3 columns.Īnd if you want to plot a data point given, say, 'c1' and 'r3', you could code i = find(strcmp(rowNames, 'r3')) % Row index The colon character (:) means several different things in MATLAB. If not, you can use cell arrays to represent row/column names, but indexing would be harder. change the second element in the first column to 9. MATLAB allows creating two types of vectors Row vectors Column vectors Row Vectors Row. Best Regards, Liu Yang If this post helps, then please consider Accept it as the solution to help the other members find it more quickly. How can I replace a matrix of zeros with other values in one. Go to your formbuilder and click on “Add question”Ĭlick on the gear icon in each column to set the question type.If you have the Statistics Toolbox, you can use the dataset objects to represent data with column and row names. Use Matrix to select a column, select average, and find each sub category average. In FreeMat, this is as simple as: -> a 1,2,3,4 a 1 2 3 4 -> a 2 ans 2 4 6 8 If you are used to something like NumPY in the Python programming language, this should seem very familiar. Create a Question Matrix in the Formbuilder ¶ Forms are set to single page layout by default - to change it, find the "layout" button in the formbuilder toolbar, select "grid-theme", save this change, and redeploy your form to make these changes live.Įnketo supports only up to 10 columns in versions less than 2.8.0, up to 13 including and after 2.8.0. Say you have > M <- matrix (1:9,3,3) M ,1 ,2 ,3 1, 1 4 7 2, 2 5 8 3, 3 6 9 > and you want to add a vector c (1,2,3) to each column. By creating a 2nd day type, weekend/weekday, you can put both into the column part of the matrix and get this result.To extract a submatrix B consisting of rows 1 and 3 and columns 1 and 2 of. This response type only works when using Enketo, utilizing the Grid-theme layout. The Importance of Comments, Add comments generously, explaining each major. In the above screenshot, theįirst two columns are select-one questions, and the third column is a number Each column can be a different question type. Kindly please help me to resolve this issue. To use this response type, define the number of rows andĬolumns you want in your matrix set and give each row and column a label or A 1 2 3 A 1 2 3 4 5 6 4 5 6 Column 1 Column 2 Columns are perpendicular to rows So how many rows and Columns does this matrix have B 1 2 3 4 5 6 7 8 So B matrix have 2 Rows and 4 Columns So whats the Size of B 2 X 4. In matrix visual, I would like to add one column called 'description' based on the category in the visual Example : Total descptionitem1 1193 5 Expected In my visual is as below Total 1193 5 In power Bi matrix visual I have added the description column into VALUES tab. For example, create a 2-by-3 matrix and add an additional row and column to it by. That display in a matrix format, whereby each cell within the matrix representsĪ separate question. MATLAB automatically pads the matrix with zeros to keep it rectangular. I have a matrix which has a number of columns M and rows X(2L/M) and I want to concatenate. The Question Matrix response type allows users to create a group of questions Cannot run a project because of Matlab API link problems.
