Question

Matlab program

A software package writes data to file that includes curly braces around each line and commas separating the values. For example, the data file, mn.txt, looks like this:

            {65.574,43.874}

{84.913,76.552}

{93.399,79.520}

{67.874,18.687}

{75.774,48.976}

{74.313,44.559}

{39.223,64.631}

{65.548,70.936}

{17.119,75.469}

{70.605,27.603}

{27.692,65.510}

{82.346,49.836}

{69.483,95.974}

{31.710,34.039}

{95.022,58.527}  

Read the data from the file mn.txt. Create a matrix that contains only the numbers and write this three-column matrix of reals to a new file.

Answer 1

initially mn.txt file is read and number of lines in the file are counted.. then by updating the current line status, numbers are read using for loop and then stored to data file in excel format. and the resulting output is as below
