In the attached data set, the rows provide daily information at a fifteen minute interval for a set of 9 variables for 31 days of January. Is there an easy way to rearrage this data, so I have 9 variables as columns and their sequence of observations for the entire month as rows. Please help!

This could almost certainly be simplified, but I think this is at least readable:
% data arranged as groups of 4 row vectors
A = [1:10; 101:110; 201:210; 301:310; 11:20; 111:120; 211:220; 311:320]
A = 8×10
1 2 3 4 5 6 7 8 9 10 101 102 103 104 105 106 107 108 109 110 201 202 203 204 205 206 207 208 209 210 301 302 303 304 305 306 307 308 309 310 11 12 13 14 15 16 17 18 19 20 111 112 113 114 115 116 117 118 119 120 211 212 213 214 215 216 217 218 219 220 311 312 313 314 315 316 317 318 319 320
% rearrange
B = [reshape(A(1:4:end,:).',[],1) ...
reshape(A(2:4:end,:).',[],1) ...
reshape(A(3:4:end,:).',[],1) ...
reshape(A(4:4:end,:).',[],1)]
B = 20×4
1 101 201 301 2 102 202 302 3 103 203 303 4 104 204 304 5 105 205 305 6 106 206 306 7 107 207 307 8 108 208 308 9 109 209 309 10 110 210 310
The webpage truncates the final output here, but it does continue in a column vector format.

readmatrix() is picking up the time headers as data, so row 1 needs to be omitted.
A = A(2:end,3:end);
Stuff like readmatrix() and readtable() might be conveniences, but it pays to make sure it's picking up the file like you expect.

Great Sir! this worked.
Sir, in another dataset (attached) the same information (biomass, coal, gas, gas cc, hydro, nuclear, other, solar, wind) is presented in a different manner (days for each fuel clubbed separately). However, I am interested in the same final output of 9 columns and 2976 rows. Could you please have a look? Shall be grateful for your help.
