This new script is used for creating a new File in MATLAB. And click on the New Script topmost option from the Home of the MATLAB window. Firstly, open the MATLAB software.
Since the format is not ascii, the file is not meant to be 'read' in this manner. Do you need to run this program every time you want to look at the output? No, you don't - not if you've saved the output to a file.The MATLAB function save is saving the structure variable S to a binary file (MAT-file) which explains the 'nonsense' that you observe in the file when opened in the Editor. Partial access of variables.Suppose that you have carried out a large computation with MATLAB - one that takes a couple of hours or so to finish.

Delete any figures before using save. If you use save to save a figure, then the function displays a warning message. MATLAB provides many different options for saving data to a file, in many different formats using commands such as fprintf this will become the k2data dormat here, the index of each structure index over the trial variable1 (1).data randn (1000, 100) variable2 (1).data randn (1000, 100) variable1 (2).data randn (1000, 100) variable2 (2).data and so on save (' data.mat ', ' variable1 ', ' variable2 ')Using save to save a figure in R2014b or later makes MAT-file inaccessible in earlier versions of MATLAB.

Mat file 'flnm.mat', the command save flnm.matIs used. Data_out.matTo save data in the. Files in this format end with the ".mat" suffix - e.g.
With M = To carry out our statistical analysis, type the following in a text editor and save as poc_stats.m load poc_data.matD = 35/((100^2)*(1000*365*24*3600)) %% change D from cm^2/kyr to m^2/sRho = sum((x-mu_x).*(y-mu_y))/((N-1)*sig_x*sig_y) Looking at a scatterplot of x with y: plot(x,y, 'o')We can compare this to the line predicted by the regression model: y_reg = a*x+b And we see that the regression model does a pretty good job of characterising the scatter of data. Such sums are done easily in MATLAB when data is stored as 1xN arrays using the 'sum' command: sum(M)Which simply adds up all of the elements in the 1xN array M. These computations involve adding up lots of numbers. To get more information, you can type help setThese data show a general decrease of POC concentration with depth (as expected), but one which is noisy.From our discussion in class, we know that we can write the POC profile predicted from the steady-state POC budget as the linear regression model y = ax + bTo estimate a and b, we'll need to compute some statistics. We can use the following command to flip the orientation of the plot set(gca, 'ydir', 'reverse')The set command can be used to change the plot in all sorts of ways - in this case, to set the y direction ('ydir') from 'normal' to 'reverse' (that is, increasing downward). Having downloaded the data, let's read them in to MATLAB load poc_data.matNote that because z increases with depth, deeper values of C are at the top of the plot.
