Error: Subscripted Assignment Dimensions Mismatch

Below I have a code that is intended to take a randomized number matrix of decimals (1 by 400) along with varibles mewfat and mewfib (both are 1 by 400). Over a for loop, I want these values to create a new variable called mewelement and to store the values produced within a new matrix.

Thank you for your help in advance.

x = min+rand(1,400)*(max-min);
[E,mewfib]=Read_Att2([drive_name,'/PHYS4115Tables/att/PMHFIB_ORIGINAL.ATT']);
[k,mewfat]=Read_Att2([drive_name,'/PHYS4115Tables/att/PMHFAT_original.att']);
for f = 1:1:100
    a = a + 1;
    mewelement(f,a) = (x.*mewfib) + ((1-x).*mewfat);
end

[per isakson]

mewelement(f,a) is obviously a scalar and the right hand side is row vector.

max and min are Matlab functions.

[Kira Bruce]

apologises. in my function, max and min are redefined to be variables that are inputed into the function.

how would I go about converting the scalar to a row vector?

[Guillaume]

You'd better rename these variables. Using max, min, sum, etc. as variables is asking for trouble. You won't be able to use these functions and you're going to confuse anybody reading your code.

You can't convert scalars to row vectors. Your code is trying to stuff a bunch a numbers (a vector) into a slot with room for just one number mewelement(f,a), this is simply not possible.

Unfortunately, since there's no comment explaining what the code is meant to be doing, we can't tell you how to fix it.

What size are you hoping mewelement to be at the end of the loop?
