save

问题 I save a matrix to a file like this: save(filepath, 'mtrx', '-ascii'); Is there a way to tell MATLAB to write 0 instead of 0.0000000e+000 values? It would be nice because it would be faster and easier to see which values differ from zero. 回答1: I suggest using DLMWRITE instead of SAVE since you're dealing with ASCII files. It will give you more control over the formatting. For example, you could create an output file delimited by spaces with a field width of 10 and 6 digits after the decimal

问题 I'm sure this is a really easy to answer question but I'm still new to cocoa. I need to save my applications data. The app has 4 text fields and each field needs to be saved into one file. Then when you open the file it needs to know what goes in what field. I'm really stuck with this. Also, I do know how to use the save panel. 回答1: A convenient way would be to use PLists: NSDictionary *arr = [NSDictionary dictionaryWithObjectsAndKeys: string1, @"Field1", string2, @"Field2", nil]; NSData

问题 I have done some pre processing for dft , and i am trying to save this image by imwrite.

问题 Can I store a dictionary using np.savez? The results are surprising (to me at least) and I cannot find a way to get my data back by key. In [1]: a = {'0': {'A': array([1,2,3]), 'B': array([4,5,6])}} In [2]: a Out[2]: {'0': {'A': array([1, 2, 3]), 'B': array([4, 5, 6])}} In [3]: np.savez('model.npz', **a) In [4]: a = np.load('model.npz') In [5]: a Out[5]: <numpy.lib.npyio.NpzFile at 0x7fc9f8acaad0> In [6]: a['0'] Out[6]: array({'B': array([4, 5, 6]), 'A': array([1, 2, 3])}, dtype=object) In [7

问题 The hibernate entity I am saving in the database (Oracle) has very complex relations, in the sense that it has many related entities. It looks something like this... @Table(name = "t_HOP_CommonContract") public class Contract { @Id private ContractPK id; @OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL) @PrimaryKeyJoinColumn private ContractGroupMember contractGroupMember; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumns({ @JoinColumn(name = "TransactionId

问题 I am using biopython package and I would like to save result like tsv file. This output from print to tsv. for record in SeqIO.parse("/home/fil/Desktop/420_2_03_074.fastq", "fastq"): print ("%s %s %s" % (record.id,record.seq, record.format("qual"))) Thank you. 回答1: That is fairly simple , instead of printing it you need to write that to a file. with open("records.tsv", "w") as record_file: for record in SeqIO.parse("/home/fil/Desktop/420_2_03_074.fastq", "fastq"): record_file.write("%s %s %s

问题 I know there is probably an answer already to this question but I haven't been able to find it yet and there is a deadline on my project. So I have made an html5 canvas and I would like to be able to do two things with one(or more) buttons. I would like the user to be able to save what he has just done by clicking on the save button and ideally I would like the image to be downloaded (as opposed to having to right click and "Save image as". This is what I have been able to do so far). I would

问题 I am in the process of making a text based game with Python, and I have the general idea down. But I am going to make the game in depth to the point where, it will take longer than one sitting to finish it. So I want to be able to make the game to where, on exit, it will save a list of variables (player health, gold, room place, etc) to a file. Then if the player wants to load the file, they go to the load menu, and it will load the file. I am currently using version 2.7.5 of Python, and am
