![]() ![]() 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. ![]() drill down all the way to get the desired result (see below) Did I answer your question Mark my post as a solution. go to subtotal tab and complete the setting as highlighted below. 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. here are the screen shot for desired result: go to format table and open 'Row Headers' and turn off step layout. I also want to add the column id to this like below: id 1 1 1 1 1 Now i. J = find(strcmp(colNames, 'c1')) % Column index Now lets see the different examples of writematrix in Matlab for better. A matrix must have the same number of elements in each row and the same number of elements in each column. 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 Rows are separated by a semicolon or a newline. If not, you can use cell arrays to represent row/column names, but indexing would be harder. Convert all the strings (that are represented by char in C) into an one-dimensional integer type array and return it to FreeMAT. You can update that if you want with something shorter but then you'd have to update the corresponding comparisons in the code as well.If you have the Statistics Toolbox, you can use the dataset objects to represent data with column and row names. char ) To FreeMAT Cell The easiest way may be to take the following three steps: Write the strings in a cell array format of FreeMAT. Select rows count as your matrix rows + 1, and columns count as your matrix columns + 3. I've used the exact copy of how you've described the operations. In the Word 2016, you can use Insert Table. where end is a special keyword in MATLAB that means the last index in the array. I created a 30x30 matrix and now I want to delete the 1st column of data and add another column replacing the deleted column (which should not replace the. Add multiples of the second row to the first and third rows to zero out the second column, except for the 1 in the (2,2) position. In this example, we will create a dataframe df and add a new column with the name Course to it. The first form: y repmat (x,n) replicates the array x on an n-times-n tiling, to create a matrix y that has n times as many rows and columns as x. Method I.1: By declaring a new list as a column df NewColumnvalue will add the new column and set all rows to that value. There are three distinct syntaxes for the repmap function. The source and destination arrays may be multidimensional. You'd need to add the new column names to the DisplayTable. Create a column vector that you can add to A to perform this task. The repmat function replicates an array the specified number of times. The code is getting overly long now, I would think. We can do it by following the same logic but the more columns you add, the less sense it makes to do it this way and the more with one different measure for each calculation. ![]()
