    regarding value problem.

    hi, i tried this one too, i will explain you clearly, i get the filename lets say vinod.csv and store it in 'fileName'as string and then i ask the user to give a value for e and lets say 200, and i use this value in the split.exe to split a file of 600 mb size to 200 each using the dos function...

    regarding value problem.

    hi, i forgot to tell you that fileName is a string where the actual file name is stored, thats why i have the quotes. but it is not working it is not splitting the file when i give directly a value instead of e, then i get it done perfectly, again help needed, thanks, vinod.b

    regarding value problem.

    hi. thanks for your replies, i have a command down here where value of e is 200 but when i run this, it is not taking e's value and it isnt working properly can someone guide me why, dos([['C:\Project\splitCSV.exe C:\Project\' fileName ' e ']]) waiting for your reply, vinod.b

    Loading of file problem.

    hi, i have used the following code to get the filename, [fileName,PathName] = uigetfile('*.csv', 'Pick one'); fileandpath = strcat(PathName,fileName); k = fileName dos(['C:\Project\splitCSV.exe C:\Project\' k ' 50']) for d = 1:3 s = [' k_ ' int2str(d) '.csv'] t = [' k_ ' int2str(d)...

    Loading of file problem.

    thank you so much it works fine, now i would like to know how to get the file name.because before running this small script, i will be executing another dos function to split csv files. here is the function, dos('C:\Project\splitCSV.exe C:\Project\a.csv 50') here a is example, but my file...

    Loading of file problem.

    hi, there is a mistake remove the load(s) command,when i say c:\project\s - s should be a_1.csv and it should fetch this file in the above directory, but it looks for s.csv and it couldnt find anything and it cannot run, so how to solve this problem. waiting for your reply, thanks, vinod.b

    Loading of file problem.

    Hi, I have a set of .csv files which i can convert using a converter which i can call thru matlab using dos command,the problem is, i have around 10 files to convert one by one and here is the code i wrote, but i couldnt get it done because in the path for the conversion if i say 's' it doesnt...

    Graph help

    I have a data of a two compressor speeds and i have to create another matrix for every 5 hrs another variable for the comp speed. then i plot the graph with x axis compressor speed and the difference of this speeds in the y axis for every 5hrs and then i have to take a data from a point for...

    Regarding code.

    thank you for your nice reply, i could able to strip off few value from one array that is comp speed. for example if i want to take values from comp speed from 4000 to 4500 rpm, i would also like to take the corresponding values of this comp speed in another array in another variable called...

    Regarding code.

    Hi, i am a mechanical engineer with basic in matlab, i am having an array of data for compressor speed and efficiency. but i would like to filter for speed of 5000 in that array,and also get the efficiencies which are in different arrays for that corresponding speed values. can anyone suggest...

    Regarding volumetric efficiency.

    Hi guys, again i would like to calculate volumetric efficiency of a screw compressor, i have mass flow rate at inlet and also temperatures and pressure at both inlet and outlet measured, and also i have compressor speed and power measured. apart from that i also have the theoretical volume and...

    Regarding volumetric efficiency.

    Hi friends, thanks for your infos, i have comp speed,pressure at inlet and outlet and temperature at inlet and outlet, can you tell me what else i need to get the volumetric efficiency using volume flow rate. etta = actual volume flow rate / theoritical volume flow rate. actual volume flow...

    Regarding volumetric efficiency.

    Hi, thanks for the info, but it is just to find the comp speed, i would like to know how to calculate the theoritical mass flow rate and the volumetric flow rate and also its difference from actual, how to calculate. it would be nice if someone can suggest, then i can put them to find the...

    Regarding volumetric efficiency.

    Hi, i am looking to calculate volumetric efficiency of a screw compressor, i have pressure ratio and temperature at outlet and inlet and comp speed and power. how to find volumetric efficiency with volume flowrate that is actual volume flow rate / theoritical volume flow rate. your...
