I created three different matrices which are A,B and C. I tried to calculate 4(AB)C but when I command it,it gives me an error. Does anyone know how can I do that?

I also need to create a system of three different linear equations with unknown that has one solution. My equations are 2x+3y=8 -x+2y=3 and 3x-4y=-5.Can anyone tell me how can I plot these lines, solve the system by using solve command and how can I solve the system using by matrices and row operations?

Hi,

I'm trying to find my way around using pdsolve. The problem I have now is how to handle the result it return me. From the psdolve help page, for example, we have the following equation returned (eq. 1.2) :

f(x, y) = _F1(x^2+y^2)

I'm an autodidact working with calculus and Maple 9.5,  I find the Maple Learning Guide more illustrative than comprehensive and the help files too oriented toward users who know more math and/or more Maple than I do.  This forum has proved helpful in responding to specific questions, but I'm looking for some books that would provide guidance on the full range of Maple's potential.  I'm not looking for a primer, but rather something as comprehensive as the help files that makes fewer assumptions about the reader's knowledge and is written

Try this out:
dt:=[2.5, 3.9, 2.9, 2.4, 2.9, .8, 9.1, .8, .7, .6, 7.9, 1.5, 1.8, 1.9, .8, 6.5, 1.6, 5.8, 1.3, 1.2, 2.7];
Statistics[Histogram](dt);

You can see the tickmark for frequency/vertical axis is wrong. The leftmost bin hits somewhere more than 0.8. Option "frequencyscale=relative " does no help. But option "discrete=true" or change some setting about bin, such as bincount ..., can help. It seems a bug? Or my understanding about histogram is not right?

I have multiple XY pairs from multiple sensor data which I would like to display on the same plot.  I can easily do this in MATLAB, but referencing Chapt 5 of the User's Manual indicates ways to plot multiple plots when plotting relations, but nothing I found pertains to actual numeric data sets.  The only plot command I found was "PointPlot" & it appears it can only plot a single data set at a time.

Any suggestions?

When I press shift+enter, I get a new line, but how do I remove the line ? (highlighting it does not always work, so I can't seem to manually delete it)
