3d Graphing Data in matlab and changing the axis values - matlab

Question

I am trying to do a 3d graph of a excel file that is 343 by 81 cells, The first column needs to be the X and the first row needs to be the Y and the remaining matrix needs to be the Z. I have the data successfully imported from excel and I create a matrix of the first column called energy (343,1)(x-axis), while creating a row matrix (1, 81) called Time Delay(y-axis) and a (343,81) matrix where the first column and row is zero called Absorbance Change(Z-axis). I've got the proper 3d graph that I need but I need the axes shown in the graph to be that of the Energy and Time Delay instead of the indices of the Absorbance Change matrix. I am putting the relevant portion of the code below as well as a picture of the graph:
EnergyString = dataArray{:, 1};
EnergyString(1,1) = {'0'};
Energy = str2double(EnergyString);
%Energy = [ Energy, zeros(343, 80) ];
TimeDelay = [ z1(1,1), z2(1,1), z3(1,1), z4(1,1), z5(1,1), z6(1,1), z7(1,1), z8(1,1), z9(1,1), z10(1,1), z11(1,1), z12(1,1), z13(1,1), z14(1,1), z15(1,1), z16(1,1), z17(1,1), z18(1,1), z19(1,1), z20(1,1), z21(1,1), z22(1,1), z23(1,1), z24(1,1), z25(1,1), z26(1,1), z27(1,1), z28(1,1), z29(1,1), z30(1,1), z31(1,1), z32(1,1), z33(1,1), z34(1,1), z35(1,1), z36(1,1), z37(1,1), z38(1,1), z39(1,1), z40(1,1), z41(1,1), z42(1,1), z42(1,1), z43(1,1), z44(1,1), z45(1,1), z46(1,1), z47(1,1), z48(1,1), z49(1,1), z50(1,1), z51(1,1), z52(1,1), z53(1,1), z54(1,1), z55(1,1), z56(1,1), z57(1,1), z58(1,1), z59(1,1), z60(1,1), z61(1,1), z62(1,1), z63(1,1), z64(1,1), z65(1,1), z66(1,1), z67(1,1), z68(1,1), z69(1,1), z70(1,1), z71(1,1), z72(1,1), z73(1,1), z74(1,1), z75(1,1), z76(1,1), z77(1,1), z78(1,1), z79(1,1), z80(1,1) ];

Answer 1

When I type help mesh in MATLAB I see, among other thins, this:
mesh(x,y,Z) and mesh(x,y,Z,C), with two vector arguments replacing
the first two matrix arguments, must have length(x) = n and
length(y) = m where [m,n] = size(Z). In this case, the vertices
of the mesh lines are the triples (x(j), y(i), Z(i,j)).
Note that x corresponds to the columns of Z and y corresponds to
the rows.
Thus, you can do
mesh(Energy, TimeDelay, AbsorbanceChange);
I don't know how you read the data from file, but there is a better way than specifying each cell individually in your code.
